Proofing dough—or giving your yeast time to expand and multiply—is paramount to producing good taste and crumb texture.
If the temperature isn’t consistent (which is often isn’t in our kitchens) it can prove to be a real problem. This handy little disk can help—it sits under your bowl of dough and heats to the perfect temperature for not-too-fast or too-slow proofing without cranking up your oven or microwave on cold days or finding a shadier spot on hot ones.
