Sufganiot (Hanukkah Jelly Doughnuts) - cooking recipe

Ingredients

1 1/4 cups slightly warm water or 1 1/4 cups slightly warm milk
1 tablespoon yeast
6 tablespoons sugar
1 teaspoon salt
1/4 cup canola oil
2 egg yolks
1 egg
1 teaspoon vanilla
1/4 teaspoon lemon extract
3 1/2 - 4 cups unbleached all-purpose flour (or half all-purpose and half bread flour)
fine sugar (for coating donuts) or sugar (for coating donuts)
1 1/2 1 1/2 cups apricot jam (optional) or 1 1/2 cups apricot jam (optional)
oil
shortening (three parts oil and one part melted shortening for frying, to fill up a good two-thirds of fryer)

Preparation

Whisk together the yeast, water and sugar, salt, oil, egg yolks, egg, vanilla and lemon extract.
Blend well and stir in most of the flour to form a soft dough.
Knead by hand, machine or in bread machine (dough setting), adding flour as needed.
The dough should have some body, not too slack, supple, smooth and elastic.
Place in a greased plastic bag and refrigerate at least 2 to 4 hours or overnight.
If you are in a hurry, allow dough to rest at least 20 minutes, then proceed.
If dough has risen at all, punch or flatten down, then pinch off pieces and form into small balls, about the size of golf balls.
Otherwise, roll dough out to about three-quarters of an inch.
Using a two and half inch or three inch biscuit cutter, cut out rounds.
Cover and let sit 15 minutes while heating oil.
In a deep fryer, or heavy dutch oven, heat about four inches of oil or a combination of oil and melted shortening.
Add the doughnuts to the hot oil (temperature should be about 375 F.) and fry until the undersides are deep brown.
Turn over once and finish frying the other side.
Lift doughnuts out using a slotted spoon and drain well on paper towels.
To fill, make a small opening and spoon in jam or jelly, or just sprinkle lightly with regular or extra fine granulated sugar by shaking doughnuts in a paper bag.
Test oil temperature: It's a good idea to try frying one doughnut to start with.
Once the doughnut seems done, take it out and cut it open to see if the inside is cooked.
