Nanny's New Orleans Red Beans & Rice

1 lb. dried kidney beans
2 quarts water
1 large onion
2 ribs celery
2-3 cloves garlic
2 slices bacon
1 crumbled bay leaf
1  tsp. salt
1/2 tsp. pepper
1/2 tsp. allspice
2 Tbsp. chopped parsley
2 Tbsp. sugar (I omit this.)
1/2-1 lb. spicy sausage (Andouille or similar)

I double this for our family of 6 so we can have guests or leftovers.

Soak beans overnight or follow quick-soak method.  Cook beans in 2 quarts of salted water (but not too salty!) until just barely done (45 minutes or so—if you overcook them, they'll fall apart later). Reserving cooking water, drain beans and rinse in cold water.

Fry bacon in Dutch oven, then remove. Using bacon drippings, sauté onion and celery.  Add garlic and parsley as onion gets clear and soft (maybe after 10 minutes).

Add 1 qt. (or more) reserved boiling liquid, cooked beans, and other spices/ingredients. Reduce heat and simmer lightly for 45 minutes.  (I've reduced this step to as little as 15 minutes in a pinch or if I've accidentally overcooked the beans in the first place.)  Mash 1/4 cup beans and return to pot for thickening. (I usually omit this step.)

Serve over cooked rice with a crusty bread and salad.
