LENTIL SOUP (LINZEN), No. 1
Soak two cups of lentils over night in cold water. Drain and add to a
sliced onion which has been browned in two tablespoons of drippings;
when these have been fried for five minutes, add three stalks of celery
cut in small pieces or some celery seed, pepper and salt to taste, and
two quarts of warm water, boil all these slowly, stirring occasionally
until the lentils are quite soft. Pass all through a sieve, return to
saucepan heat again and serve.
