Dulce de Leche

Ingredients

• 1 gallon milk
• 1 vanilla bean
• 4.5 cups white sugar
• 1 teaspoon baking soda

Steps

1. Bring milk to a boil in a large saucepan over medium-high heat. Remove from heat; strain through cheesecloth. Return to the saucepan.
2. Cut vanilla bean in half; scrape seeds into milk. Stir in sugar; heat over medium-high heat, stirring constantly, until sugar is dissolved. Stir in baking soda just as milk mixture begins to boil. Reduce heat to medium, stirring constantly, until mixture thickens, a wooden spoon drawn through mixture leaves the bottom of the pan visible, and mixture is light brown. Remove pan from heat.
