The best way to improve everyday cooking is to learn how to know your pan is actually ready before adding food. A cold pan can make meat stick, vegetables turn watery, and potatoes brown slowly. For stainless steel, a few water drops should bead and move across the surface. For oil, look for a light shimmer, not heavy smoke. Different foods need different heat levels, so eggs and fish need gentler heat than steak or mushrooms. A proper preheat improves browning, texture, and cooking control.
