Traditional Doughnut

Why This Traditional Doughnut Works

As the dry and wet bowls come together, the flour soaks up the milk and egg and forms a soft dough instead of a runny batter. Baking powder and egg trap tiny air pockets inside that dough. Nutmeg and sugar spread through it so every bite tastes the same. The melted butter coats the flour a bit, so the dough stays tender instead of tough when it hits the hot oil.

Once the cut doughnuts go into 375°F oil, the outside cooks fast and sets into a thin shell. At the same time, the baking powder wakes up from the heat and the water in the milk and egg turns to steam. Those gases push against that soft shell and puff the doughnuts up. Inside, the dough cooks through and firms up, but the butter and steam keep it soft and a little moist. By the time they are golden brown, the outside has a light crunch and the inside stays fluffy instead of dense or greasy.

Mistakes To Avoid

Letting the oil get too cool makes the doughnuts soak up fat instead of puffing. The dough sits in the oil longer, the outside never really crisps, and the centers can stay a bit doughy while the whole thing turns greasy and heavy.

When the oil is too hot, the outside browns fast while the inside is still raw. The doughnuts look done after a minute or so, but once bitten into, the middle is gummy and undercooked.

Overmixing the dough after the wet ingredients go in works the flour too much. The dough becomes tight instead of soft, and the fried doughnuts turn out tough and bready instead of light.

Rolling the dough too thin changes how it fries. Thin doughnuts cook through very fast, harden in the oil, and end up dry and crisp instead of soft and fluffy inside.

Adding a lot more flour while rolling can also cause trouble. The extra flour stiffens the dough, so the doughnuts don’t puff well and come out dense with a slightly dry bite.
