Storage: Keep the mix in the refrigerator for up to 6 months. Ensure the container is tightly sealed to prevent moisture absorption.
Substitutions: You can use shortening or lard instead of vegetable oil for a richer flavor, though the texture may be slightly crumblier.
Variations: Add 1-2 tablespoons of sugar and 1 teaspoon of cinnamon to the mix for sweet cinnamon biscuits.
Tips: Do not overwork the dough when adding water, as this can make the biscuits tough. Handle gently for the flakiest result.
