Tips for Adapting Recipes
- It may be easier to make the entire recipe for baked goods and freeze half.
- When reducing recipes, you may need to use smaller saucepans, skillets and baking pans.
- The standard size egg for recipes is the large egg. To halve an egg, break it, mix it together with a fork and use 2 tablespoons. Refrigerate the rest and use in an omelet or scrambled eggs within two to four days.
- When using a different pan size, try and keep the depth of food the same.
- If halving a recipe:
- Use an 8x8 or 9” round pan if the recipe calls for 9x13.
- Use an 8x5” loaf pan if the recipe calls for 8x8 or 9” round pan.
- Use 3x5 loaf pan if the recipe calls for 8x5 loaf pan
- To help divide recipes, remember:
- 1 cup = 16 Tablespoons
- 1 Tablespoon = 3 teaspoons
- 1 cup = 8 fluid ounces
- 1 fluid ounce = 2 Tablespoons
- 1 pound = 16 ounces (weight)
- 1 pint = 2 cups
- 2 pints = 1 quart
- 1 quart = 2 pints
- The time for baking smaller amounts of food may be less. Rely on visual clues and start checking for doneness early.
Reduce the oven temperature by 25°F when substituting a glass pan for a metal one.
