I made a delicious Pea & Mint Risotto the other day. When discussing it with others, most where shocked that I would use frozen peas. I was surprised to learn how many people think that frozen veggies are no good.
The fact of the matter is that if you are not growing your own peas or getting them from the vine that day, you are better off using frozen. Frozen fruits and vegetables are fresh fruits and vegetables that have been blanched (cooked for a short time in boiling water or steamed) and frozen within hours of being picked. Further, frozen fruits and vegetables are processed at their peak in terms of freshness and nutrition. Many experts have found that frozen vegetables such as peas are better for you than fresh or canned.
