Beurre Mani'e

A butter and flour paste used for thickening soups or stews without altering the taste.

In a bowl, mash together:
1 Tablespoon softened butter
1 Tablespoon all purpose flour

Add a cup of soup or stew liquid and mix until the butter and flour mixture is incorporated completely into the liquid. Stir the mixture back into the soup or stew and bring to a boil to thicken.

Note: This works and by using any broth and a few left over veggies as an extender can change a small quantity meat into a rich something over rice or toast.
