Preparation & Safety

How to wash and prepare kale

Because kale has higher surface permeability, synthetic pesticides easily adhere to the skin. To reduce exposure by up to 80–90%, soak in a 1% baking soda water solution (1 tsp baking soda per 2 cups cold water) for 12 to 15 minutes, then rinse vigorously under running water.
