Butter substitutes are alternatives used in cooking and baking to replace traditional butter. They can be made from various ingredients, including oils, margarine, and even plant-based options like coconut oil or avocado. These substitutes can help reduce saturated fat intake or cater to dietary restrictions, such as lactose intolerance or vegan diets. When choosing a butter substitute, it's essential to consider the recipe and desired flavor. For instance, olive oil works well in savory dishes, while applesauce can add moisture and sweetness in baked goods. Experimenting with different substitutes can lead to delicious and healthier meals!
