Tomato puree is a staple ingredient in countless kitchens worldwide, offering a concentrated tomato flavor and thickening properties to sauces, soups, and stews. But what happens when you’re in the middle of cooking and realize you’re out? Can you substitute canned tomatoes? The short answer is yes, but with some considerations. This article dives deep into the nuances of using canned tomatoes as a tomato puree alternative, exploring the different types of canned tomatoes, their flavor profiles, preparation methods, and best use cases.
Understanding Tomato Puree and Canned Tomatoes
To effectively substitute one ingredient for another, it’s crucial to understand their fundamental differences. Tomato puree is essentially cooked tomatoes that have been strained to remove skins and seeds, then cooked down to a thick, smooth consistency. This process concentrates the tomato flavor and creates a versatile base for many recipes.
Canned tomatoes, on the other hand, come in various forms, each with unique characteristics:
-
Whole Peeled Tomatoes: These are usually packed in tomato juice or puree. They offer a bright, fresh tomato flavor but require more preparation.
-
Diced Tomatoes: Pre-cut for convenience, they may include added seasonings or calcium chloride to maintain their shape.
-
Crushed Tomatoes: These offer a texture between diced and puree, providing a good balance of flavor and body.
-
Tomato Paste: The most concentrated form of canned tomatoes, with an intense flavor and thick consistency. While not a direct substitute, it can be used in conjunction with other canned tomato varieties.
When and How to Substitute Canned Tomatoes for Tomato Puree
The suitability of canned tomatoes as a tomato puree substitute depends largely on the recipe and the desired outcome. For dishes where a smooth texture is paramount, such as a creamy tomato soup, more processing will be needed. In recipes where a chunkier texture is acceptable, like a rustic pasta sauce, the substitution is more straightforward.
Choosing the Right Type of Canned Tomatoes
The first step is selecting the most appropriate type of canned tomatoes. Whole peeled tomatoes are generally the best option because they offer the most control over the final texture and flavor. Diced tomatoes can work, but you’ll need to be mindful of any added seasonings. Crushed tomatoes are a closer match in terms of consistency, reducing the amount of processing required.
Preparing Canned Tomatoes for Substitution
Regardless of the type of canned tomatoes you choose, some preparation is usually necessary.
-
Draining: Drain the canned tomatoes to remove excess liquid. This will help concentrate the tomato flavor and reduce cooking time.
-
Crushing or Chopping: If using whole peeled tomatoes, crush them by hand or roughly chop them. Diced tomatoes are already pre-cut.
-
Simmering: Simmer the tomatoes in a saucepan over medium heat for at least 15-20 minutes. This will help them break down and release their flavors.
Achieving a Smooth Texture
If a smooth texture is desired, you’ll need to further process the cooked tomatoes. There are several methods you can use:
-
Immersion Blender: An immersion blender is a convenient tool for pureeing the tomatoes directly in the saucepan. Be careful to avoid splattering.
-
Regular Blender: Transfer the cooked tomatoes to a regular blender and blend until smooth. Allow the tomatoes to cool slightly before blending, and vent the lid to prevent pressure buildup.
-
Food Processor: A food processor can also be used to puree the tomatoes, although it may not achieve as smooth a result as a blender.
-
Food Mill: A food mill is an excellent tool for removing skins and seeds while pureeing the tomatoes, resulting in a very smooth and refined texture.
Adjusting Consistency and Flavor
After pureeing the tomatoes, you may need to adjust the consistency and flavor to match that of tomato puree.
-
Thickening: If the puree is too thin, continue simmering it over low heat until it reaches the desired consistency. You can also add a small amount of tomato paste to thicken it further.
-
Thinning: If the puree is too thick, add a little water or tomato juice to thin it out.
-
Seasoning: Taste the puree and adjust the seasoning as needed. Add salt, pepper, sugar (to balance acidity), and any other herbs or spices that complement the recipe. Remember that canned tomatoes may already contain salt, so taste before adding more.
Specific Recipe Considerations
The best way to substitute canned tomatoes for tomato puree also depends on the recipe.
-
Pasta Sauce: For a simple pasta sauce, crushed tomatoes can often be used directly without much alteration. If you prefer a smoother sauce, puree them first. You might also add a tablespoon or two of tomato paste to enrich the flavor and deepen the color.
-
Soup: Soups often benefit from the bright acidity of fresh tomatoes. Whole peeled or crushed tomatoes work well, and pureeing them adds body to the soup.
-
Stew: Stews are forgiving and can handle a chunkier texture. Diced or crushed tomatoes are a good choice, and the long cooking time will allow the flavors to meld together.
-
Pizza Sauce: Pizza sauce typically requires a very smooth texture and concentrated flavor. Using whole peeled tomatoes that have been pureed and simmered with tomato paste is the best approach.
Advantages and Disadvantages of Using Canned Tomatoes as a Substitute
There are both pros and cons to using canned tomatoes in place of tomato puree.
Advantages:
- Availability: Canned tomatoes are readily available in most grocery stores.
- Cost-Effectiveness: Canned tomatoes are often more affordable than tomato puree.
- Versatility: Canned tomatoes can be used in a wider range of recipes.
- Control over Ingredients: You can choose canned tomatoes with no added salt or sugar, giving you more control over the final flavor.
Disadvantages:
- Preparation Time: Using canned tomatoes requires more preparation than simply opening a can of tomato puree.
- Consistency: Achieving the same smooth consistency as tomato puree can be challenging.
- Flavor Variations: The flavor of canned tomatoes can vary depending on the brand and variety.
- Added Ingredients: Some canned tomatoes may contain added salt, sugar, or other ingredients that you may not want in your recipe. Always check the label carefully.
Tips for Success
To ensure a successful substitution, keep these tips in mind:
-
Choose high-quality canned tomatoes. Look for brands that use vine-ripened tomatoes and have minimal added ingredients.
-
Taste as you go. Adjust the seasoning and consistency to match your preferences.
-
Don’t be afraid to experiment. Try different types of canned tomatoes and preparation methods to find what works best for you.
-
Consider adding other flavor enhancers. A pinch of sugar, a splash of balsamic vinegar, or a teaspoon of dried herbs can all help to boost the flavor of your tomato puree substitute.
-
Simmer for longer. Allowing the tomatoes to simmer for a longer period of time will help them break down and develop a richer flavor.
Flavor Profiles and Considerations
Understanding the subtle nuances of tomato flavor can help you fine-tune your substitution. Different varieties of tomatoes have distinct flavor profiles, and the canning process can further alter these flavors. Some canned tomatoes may be sweeter, while others may be more acidic. Experimenting with different brands and varieties will help you find the ones you prefer. Additionally, factors like the ripeness of the tomatoes at the time of canning and the type of packing liquid used can influence the final flavor. Tomatoes packed in tomato juice will generally have a more intense tomato flavor than those packed in water. Tomatoes packed with basil or other herbs can add an extra layer of flavor to your dish.
Ultimately, substituting canned tomatoes for tomato puree is a viable option, especially when you consider the specific type of canned tomato, the recipe, and the desired outcome. With careful preparation and attention to detail, you can achieve results that are just as delicious, if not more so, than using tomato puree. By understanding the nuances of each ingredient and mastering the techniques involved, you can confidently navigate any recipe, even when faced with unexpected ingredient shortages. The key is to be adaptable, creative, and willing to experiment in the kitchen.
The Verdict: A Worthwhile Substitution
While tomato puree offers convenience and a predictable consistency, canned tomatoes provide versatility and the opportunity to customize flavors. By understanding the differences between the two, you can confidently use canned tomatoes as a substitute and create delicious, flavorful dishes. So, the next time you find yourself without tomato puree, don’t hesitate to reach for that can of tomatoes – with a little effort, you can achieve excellent results. Embrace the flexibility of cooking, experiment with different techniques, and enjoy the process of creating delicious meals.
Can I directly substitute canned tomatoes for tomato puree in a recipe?
Canned tomatoes, whether diced, crushed, or whole, cannot be directly substituted for tomato puree without some adjustments. Tomato puree is a smooth, concentrated product, while canned tomatoes have a higher water content and a different texture. Using them interchangeably will significantly alter the consistency and flavor profile of your dish, often resulting in a thinner and less intense tomato flavor.
To use canned tomatoes as a substitute, you’ll need to reduce the liquid content and break down the tomato chunks. This can be achieved by simmering the canned tomatoes in a saucepan, stirring occasionally, until the excess liquid evaporates and the tomatoes have softened. Alternatively, you can use an immersion blender or a food processor to achieve a smoother consistency before simmering.
What kind of canned tomatoes work best as a substitute for tomato puree?
Diced and crushed canned tomatoes are generally the best options for substituting tomato puree because they’re already partially broken down. Whole canned tomatoes can also work, but they require more effort to break down and may contain tough skins that need to be removed. Avoid using flavored canned tomatoes (e.g., with basil or garlic) as the added flavors might clash with your recipe’s intended flavor profile.
When choosing canned tomatoes, look for varieties that are labeled “plum” or “Roma” as these typically have a meatier texture and fewer seeds than other types of tomatoes. San Marzano tomatoes, if available, are considered a premium option due to their rich flavor and low acidity. Opt for tomatoes canned in juice rather than sauce or paste, as the latter can contain unwanted added ingredients.
How do I adjust the recipe when substituting canned tomatoes for tomato puree?
The primary adjustment when substituting canned tomatoes for tomato puree is to account for the increased liquid content. Since canned tomatoes contain more water, you will need to reduce the overall amount of liquid in the recipe or simmer the tomatoes for a longer period to evaporate the excess moisture. This will help you achieve the desired consistency.
Start by using roughly twice the amount of canned tomatoes as the tomato puree called for in the recipe, then simmer the sauce or dish for an extended period to allow the liquid to reduce and the flavors to concentrate. Taste frequently and adjust seasonings as needed, as the flavor of canned tomatoes may differ slightly from tomato puree. You may also need to add a touch of sugar to balance the acidity of the tomatoes.
Can I use a blender to make canned tomatoes more like tomato puree?
Yes, using a blender, either an immersion blender or a regular countertop blender, is an effective way to break down canned tomatoes and achieve a smoother consistency closer to that of tomato puree. This step is particularly helpful if you’re using whole or diced canned tomatoes, as it reduces the chunks and creates a more uniform texture.
However, blending alone won’t completely replicate tomato puree because the blended tomatoes will still have a higher water content. After blending, it’s crucial to simmer the tomatoes in a saucepan to reduce the excess liquid and concentrate the flavors. Blending before simmering significantly shortens the overall cooking time and results in a smoother final product.
What are the benefits of using canned tomatoes instead of tomato puree?
One potential benefit of using canned tomatoes is that they often have a fresher, brighter flavor than tomato puree, which can sometimes taste slightly cooked or processed. Canned tomatoes also offer more versatility in terms of texture; you can choose from diced, crushed, or whole, allowing you to tailor the consistency of your dish to your preference.
Another advantage is that canned tomatoes are generally more readily available and often less expensive than tomato puree, especially if you’re looking for specific brands or varieties. Plus, using canned tomatoes gives you greater control over the ingredients in your sauce, allowing you to avoid any unwanted additives or preservatives that might be present in some commercially prepared tomato purees.
How long can I store cooked tomato sauce made with canned tomatoes?
Cooked tomato sauce made with canned tomatoes can be safely stored in the refrigerator for 3-4 days in an airtight container. Allow the sauce to cool completely before refrigerating to prevent condensation and maintain its quality. Label the container with the date of preparation to ensure you use it within the recommended timeframe.
For longer storage, you can freeze the cooked tomato sauce for up to 2-3 months. Portion the sauce into freezer-safe containers or bags, leaving some headspace for expansion during freezing. Thaw the sauce in the refrigerator overnight before reheating. Note that freezing may slightly alter the texture of the sauce, but the flavor should remain largely intact.
Does the type of canned tomatoes (organic vs. non-organic) affect the outcome?
Whether you use organic or non-organic canned tomatoes is largely a matter of personal preference and dietary considerations. Organic canned tomatoes are grown without synthetic pesticides and fertilizers, which some people may prefer for health or environmental reasons. However, in terms of flavor and consistency, there is typically not a significant difference between organic and non-organic canned tomatoes.
The key factors that influence the outcome of your dish are the variety of tomatoes used (e.g., plum, Roma, San Marzano), the canning process, and the overall quality of the product. Choose canned tomatoes that are free from artificial additives, have a vibrant color, and a pleasant aroma, regardless of whether they are labeled organic or not.
