There are different rice water recipes, but we recommend using only one tried and tested method. To make rice water with this recipe, take uncooked rice and add four times as much water to the mixture. For example, you'll need two cups of water for a half cup of rice. Now, heat the water following any boiling method. Once done, strain the boiling water from the rice. Now, take a glass bottle in which you can store rice water and let it sit for a few days. The fermentation process takes about two weeks, and you'll have rice water suitable for protein treatment after that!
