Dulce de Leche

Combine Ingredients: In a large, heavy-bottomed pot, mix the milk, sugar, and baking soda. Cook over low heat, stirring constantly to prevent burning.

Thicken: Continue to cook, stirring frequently, until the mixture becomes thick and caramel-colored, about 1-2 hours.

Flavor: Stir in the vanilla extract.

Cool: Let the dulce de leche cool, then transfer to a jar. It will thicken further as it cools.
