Condensed Milk

In a heavy-bottomed saucepan, combine the milk and sugar over medium heat. Stir until the sugar dissolves completely.

Once the sugar has dissolved, reduce the heat to low and let the milk simmer gently. Stir the mixture occasionally to prevent it from sticking.

Allow the mixture to simmer until it reduces by half and thickens to a consistency similar to cream, which should take approximately 1 to 2 hours.

If using, stir in a pinch of baking soda to help prevent crystallization.

Once thickened, remove from heat and let it cool down to room temperature. Pour into a sterilized jar or container.
