Can I use broccoli leaves in place of broccoli florets in recipes?
While broccoli leaves can be used in place of broccoli florets in some recipes, they have a slightly different texture and flavor. The leaves are typically more bitter and earthy than the florets, with a slightly tougher texture. However, they can be used in many recipes, such as soups, stews, and sautéed dishes, where their unique flavor and texture can add depth and interest.
