Donuts Filled with Strawberry Jam
Mix the flour with baking powder and salt in a bowl. Add the eggs, salt, sugar, cinnamon, lemon zest, oil and baking powder to the flour, and knead into a smooth dough. Let the dough rest for 1 hour in a warm place.
Divide the dough into portions and shape each portion into balls. Pour strawberry jam in a syringe. Heat shortening in a pan and fry the balls until brown on both sides. Drain the fried balls or donuts on kitchen paper and serve sprinkled with powdered sugar. Garnish with cinnamon.
