Step 1

In a large bowl whisk the eggs and three tablespoons of sugar together.

Step 2

Add the oil, liqueur or extract, baking soda, and baking powder. Whisk until combined.

Step 3

Add the milk and lemon zest and whisk until smooth.

Step 4

Add the flour little by little, until you have a slightly sticky dough. It can't be too sticky to work with, but if you add too much flour the donuts can come out hard. Add extra flour if needed to achieve the right consistency.

Step 5

Heat oil in a wide, heavy frying pan.

Step 6

While heating, form the donuts. Grease your hands with oil and grab a small handful of dough. Poke a hole in the center with your finger and carefully stretch until the hole is about 1 inch (2.5 cm.) in diameter.

Step 7

Gently add the formed donuts into the hot oil a few at a time. Don't overcrowd the pan. Brown on one side and then flip and brown the other.

Step 8

Once fried, remove with a slotted spoon and place on a plate of paper towels.

Step 9

Cover with sugar on all sides while still hot. Enjoy!
