Place 1 cup of uncooked rice into a zip-top bag or container with lid.
Add in 1 tsp of vinegar or rubbing alcohol and a few drops of food coloring to the rice.
Seal the bag and shake until rice is evenly colored.
Spread the rice on parchment paper or baking sheet in a thin layer and let it dry.
Once dry, store the rice in an airtight container for future use!
