If the hallmark of a great cook is consistently turning out delicious food, cooking to exact temperatures is the surest way to nail those dishes every time. Chefs rely heavily on temps for sous vide cooking, where food in vacuum-sealed bags poaches for hours in water heated to a specific temperature so the ingredients are guaranteed to be perfectly cooked. The same principle applies at home. Here, we share temperatures that bring us brilliant results for slow-roasted meat, creamy custard, fresh-baked bread, crispy tempura green beans, poached fish, and more. So grab your digital thermometer and learn how it can take your cooking to the next level.
