4 to 4 1/2 cups white bread flour, plus more for dusting
1 teaspoon salt
2/3 ounce (.6 ounce) cake fresh yeast or 1 envelope dry active yeast (2 1/2 teaspoons)
1 cup lukewarm milk
2 tablespoons granulated sugar, plus more for dusting
2 large eggs, beaten
2 tablespoons unsalted butter, melted and cooled
1/2 cup preserves of choice
Vegetable oil, for frying
Cinnamon and sugar, for rolling doughnuts
In the bowl of a mixer, combine 4 cups flour and salt. Add the yeast.
In a small bowl, combine the milk and 2 tablespoons sugar. Add with the remaining
milk to the flour. (If using dry yeast, mix the yeast with 2 tablespoons of the
milk and 2 tablespoons sugar and let sit until foamy, about 5 to 10 minutes and
add to the flour.)
Add the eggs and butter to the flour mixture. Begin to mix the ingredients into
a soft, but not sticky, dough. Add a little extra milk, 1 tablespoon at a time.
Work in extra flour, 1 tablespoon at a time. Turn the dough out onto a lightly floured
surface and knead until smooth and elastic. (You can do this in a mixer fitted with
a dough hook.) Transfer the dough to a lightly oiled bowl, cover, and let rise until
doubled in size, about 2 hours.
Punch down the risen dough. Turn out onto a lightly floured surface and knead
for a few seconds. With a lightly floured rolling pin, gradually roll out the dough
to about 1/2 inch thick. When rolling dough, let it rest periodically to relax.
Cut out into 3- to 4-inch rounds with a lightly floured biscuit cutter. Re-roll
the scraps to make more rounds. Place the doughnuts on lightly floured baking sheets,
spacing them apart, and cover lightly with a dry towel. Let rise in a warm spot
until doubled in size, about 20 minutes.
Transfer the risen doughnuts to a heavy pot filled 3 inches high with vegetable
oil at 350 degrees F. Fry the doughnuts, a few at a time, until golden and puffed,
turning frequently, 5 to 7 minutes.
Lift the doughnuts from the oil using a slotted spoon and roll on a plate lined
with granulated sugar and cinnamon mixed together. Let cool slightly and fill a
pastry bag, fitted with a 1/2-inch round tip with jelly preserves. Insert the tip
into the end of each doughnut and pipe approximately 1 to 2 teaspoons preserves
into them and serve.
