Cooking Methods
Canned pigeon peas are already cooked, so they can be added directly to dishes without further cooking. However, simmering them in sauces or stews can enhance their flavor. They are great for dishes like:
- Rice and peas (a Caribbean staple)
- Soups and stews
- Salads
- Curries
- Stuffings
Flavor Pairings
Pigeon peas pair well with a variety of flavors, including coconut milk, ginger, garlic, onions, peppers, and various spices. Experiment with different flavor combinations to find your favorites.
Storing Canned Pigeon Peas Properly
Proper storage is essential to maintain the quality and safety of canned pigeon peas.
Unopened Cans
Store unopened cans of pigeon peas in a cool, dry place away from direct sunlight and heat. Properly stored canned goods can last for several years.
