You can substitute lard or butter for shortening in pastry or biscuit recipes. You can substitute butter for shortening in many cookie recipes, but you will get a flatter, crisper texture. If you are looking for healthy substitutes, it really depends on the recipe. Butter substitutes don’t always work well in baked recipes, as they contain more water than butter or shortening and can cause crumbly textures. You might try substituting small amounts of the shortening with butter substitutes to see how it works in your recipes.
