Either dried peas or canned green peas may be used to make cream-of-pea soup. If dried peas are used, they must first be cooked soft enough to pass through a sieve. The flavor is quite different from that of green peas. With the use of green peas, a fair amount of both protein and carbohydrate is added to the soup, but more protein is provided when dried peas are used.
Sufficient to serve four.
Make white sauce of the milk, flour, and butter. Put enough freshly cooked or canned peas through a sieve to make 1/2 cupful of purée. Then add the pea purée, the salt, and the pepper to the white sauce. Heat thoroughly and serve.
