Cooking Guides

Practical reference guides for measurements, substitutions, recipe scaling, and food safety.

These practical guides are designed to help when a recipe is brief, uses unfamiliar measurements, calls for an ingredient you do not have, or needs to be adjusted for a different number of servings.

Recipe Measurements and Conversions

US volume relationships, metric approximations, measuring dry and liquid ingredients, and why weighing is often better for baking.

Common Ingredient Substitutions

Practical swaps for dairy, eggs, fats, flours, leaveners, herbs, and pantry staples—with notes about when a substitution may change the result.

How to Scale a Recipe

A reliable process for changing yield, choosing pan sizes, adjusting seasonings, and estimating cooking time.

Food Safety Basics

Four core food-safety steps, thermometer use, leftovers, and links to current USDA and FoodSafety.gov guidance.
