The best onion soup

INGREDIENTS

• 1 tablespoon of butter or lard
• 1 teaspoon of sugar
• 1 tablespoon of all-purpose flour
• 8 large onions broth
• olive oil
• salt
• black pepper

METHOD

1. We slice the onions into rings and place half of them in heated butter or oil. We stir until they break down and fry until golden brown and caramelized. Then we add the remaining half. When softened, we add sugar and let it dissolve.
2. Later, we add flour and stir. Once the flour absorbs the fat, we pour in a bit of broth to prevent the onions from burning. Then we add the rest of the broth, season to taste, and let it simmer for about 20 minutes.
3. The soup can be served with a baguette and cheese, and optionally flavored with garlic.
