Slice the bread into thick slices.

In a saucepan, bring the milk to a boil with sugar, cinnamon sticks, and the lemon and orange peels.

Once the milk has boiled, soak the bread slices in the milk mixture.

Beat the eggs in a bowl, then dip the milk-soaked bread slices into the eggs to coat them.

Heat a skillet with plenty of oil.

Fry the bread slices after coating them in milk and egg until golden brown.

On a plate, mix sugar with ground cinnamon, then coat the fried torrijas in the mixture.

Arrange the torrijas on a serving plate and let them cool before eating.
