4 c. milk
1 1/4 c. sugar
1/4 t. baking soda
1 t. vanilla
Stir together milk, sugar, and baking soda in a 3- to 4-quart heavy saucepan.
Bring to a boil, then reduce heat and simmer uncovered, stirring occasionally, until caramelized and thickened, about 1 1/2 - 1 3/4 hours.
(After about an hour, stir more often as milk caramelizes, to avoid burning.)
Stir in vanilla.
Transfer to a bowl to cool.
Makes about 1 1/2 cups.

Dulce de leche will keep for a couple of weeks, refrigerated. It would be great stirred into coffee or cocoa, spread on toast, or warmed and drizzled on ice cream. Try it with peanut butter on a sandwich (surely the top trade at the school lunch table).
