The term "wet ingredients" refers to any ingredient that is used in a recipe and is typically liquid or semi-liquid. These can include liquids such as milk, water, oil, broth, or stock; emulsions like mayonnaise or salad dressing; and sauces or condiments like soy sauce, mustard, or honey. Wet ingredients are essential in many recipes to help bind the mixture together, add moisture, and enhance flavor. They can be mixed into the dry ingredients or added separately depending on the specific instructions of a given recipe.
