Thai food. The very words conjure images of fragrant curries, vibrant street food, and a symphony of flavors that dance on the palate.

The Foundation: Common Vegetables in Thai Cooking
Many vegetables commonly found in Western cuisine also find a welcome home in Thai dishes. Their familiar flavors provide a comforting base upon which the more exotic and pungent Thai spices can build their magic.
Cabbage and its Culinary Versatility
Cabbage, in its various forms, is a staple. Green cabbage, often shredded thinly, adds a refreshing crunch to salads and noodle dishes like Pad See Ew.

Carrots, known for their vibrant orange hue and gentle sweetness, are frequently used in Thai cooking. They are often julienned or sliced thinly and added to stir-fries, curries, and salads. Carrots provide a visual appeal and a subtle sweetness that balances the savory and spicy elements of many Thai dishes.
Onions: Aromatic Base for Flavor
Onions, both yellow and red, form the aromatic foundation for countless Thai recipes. They are typically sautéed at the beginning of the cooking process, releasing their fragrant oils and creating a base upon which other flavors can build. Red onions, with their slightly sharper flavor, are also often used raw in salads and as a garnish.
Garlic: Pungent Punch of Flavor
