Glazed Donut

Fried sweet dough came to America with Dutch settlers as 'olykoeks,' or oil cakes, and the ring shape with a hole became standard in the nineteenth century. The often-told story that a sea captain named Hanson Gregory punched out the first hole in 1847 to fix the gummy center is now generally regarded as apocryphal, so it should be passed on as legend rather than fact. The donut became a mass-market food after Adolph Levitt, a Russian immigrant in New York, invented an automatic doughnut machine around 1920, mechanizing frying. The glazed yeast donut as an icon is closely tied to Krispy Kreme, whose founder Vernon Rudolph began frying his original glazed doughnuts in Winston-Salem, North Carolina, in 1937.

A fresh glazed donut is feather-light and pillowy, tearing into soft, fluffy strands with a faint chew from the yeast. The fried surface is thin and delicate, and the glaze gives a sweet, glassy crackle that dissolves instantly. Warm from the fryer, it almost melts in the mouth, with the gentle flavor of fried, lightly sweet dough and vanilla. The contrast of the crisp-glazed exterior and the airy interior is the whole pleasure; left to go cold, it loses much of its magic.

Yeast is what sets this donut apart: it ferments the dough, producing carbon dioxide that inflates a gluten network into a light, open, stretchy crumb, the same biology as bread. The dough is kneaded to develop gluten, then proofed twice so it rises and relaxes before frying. Frying at around 175 to 190°C cooks the ring in a minute or two — the wet dough sets fast at the surface through the Maillard reaction while steam inside keeps the crumb soft and the hole ensures the center cooks through. The glaze is a simple sugar syrup applied while the donut is hot, so it soaks slightly into the surface and then sets as a thin, glassy shell as it cools.
