Low Heat: food that needs to cook through without getting too crispy or browned. It's great for eggs, pancakes, delicate seafood, and thicker cuts of meat that will take an extra-long time to cook.
Medium Heat: food that requires a perfect, golden-brown sear, but needs a little extra time to cook all the way through, such as: chicken breasts or thighs, thicker steaks, seafood, and most vegetables.
High Heat: thinner cuts of meat that would benefit from a seared flavor, but have the potential to dry out quickly, such as: smashed burgers, hibachi, fajitas, stir fry, and thinly cut steaks.
