Sourdough Donuts

Instructions

1. Mix the sourdough starter, milk, eggs, butter, sugar, salt, and 240g of flour in a large bowl until smooth.
2. Add the rest of the flour and mix until the dough pulls away from the sides of the bowl.
3. Cover the dough and let it rest for 8-12 hours, or until it doubles in size.
4. On a floured surface, roll out the dough to about half an inch (about 1.5cm).
5. Cut out the donuts with a cookie cutter, by hand, or roll the dough into balls.
6. Cover the cut donuts and let them rise until they slightly puff up, about 1 hour.
7. While the cut doughnuts rest, make the sugar glaze by melting the sugar with 2 tablespoons of milk in a small saucepan.
8. Heat oil in a large pot until it reaches 190°C (375°F). Fry the doughnuts, flipping once, until golden brown.
9. Drain the donuts on paper towels and then dip in the sugar glaze.
