Spiced Sweet Potato Doughnuts (Spudnuts)

The secret of the sweet potato doughnut (or 'Spudnut') lies in the starch. Potato starch absorbs and retains moisture, keeping the doughnut soft for days, unlike traditional versions that dry out quickly. Due to the vegetable's natural sweetness and soft texture, less sugar is needed in the dough.

Instructions

1

Mix the flour with the spices, sugar, salt, and yeast.

Tip: Distribute spices in the flour, not the liquid.

Tip: Important: the potato must not be hot, or it will cook the egg and kill the yeast.
3

Proof for 60 minutes, then shape and rest again for 30 minutes.

Tip: Due to the starch, the dough structure is very soft, handle with care.
4

Fry in 340°F oil.

Tip: Due to sugar content (potato + sugar), it may brown faster.
5

Serve drizzled with honey or dusted with powdered sugar.

Tip: Honey pairs well with earthy flavors.
