The primary ingredient in peach cobbler is peaches. Fresh, ripe peaches are often used, although canned or frozen peaches can also work well in a pinch. The fruit is typically sliced and mixed with sugar and spices, like cinnamon or nutmeg, to enhance its flavor. This peach mixture is then covered with a biscuit-like or cake-like topping before baking. The combination of warm, juicy peaches and a crispy, golden topping makes peach cobbler a delicious dessert that is often enjoyed during the summer months when peaches are in season. It's a classic dish in Southern cooking.
