Place vinegar in a measuring cup. Add milk to the vinegar to the 1 cup mark. Set aside for 10 minutes. Preheat oven to 450° Fahrenheit.
Place flour in a food processor. Cut butter into pieces and add to the flour. Pulsate until the butter is pea-sized.
Add milk mixture and process until the milk has been combined with the flour. The mixture will be “sticky.”
Pat out mixture on floured surface until about 1 inch thick. Cut with a biscuit cutter (or drinking end of cup). Place the biscuits on a baking sheet or baking stone.
Bake for 10-12 minutes or until golden brown.

Notes
These biscuits are a great alternative for times that you don't have buttermilk. If you DO have buttermilk, you can use it in place of the milk and vinegar.
