Recipe Conversions

When a recipe calls for 32 oz of liquid, you can measure it as:

Common Recipe Applications

Soups and Stews:

Most soup recipes start with 32 oz (1 quart) of broth as the base. This typically serves 4 people with 8 oz portions.

Sauces and Gravies:

Large batch sauces often call for 32 oz of tomatoes, stock, or cream as the liquid component.
