Citrus zest to intensify flavor


Add extra flavor to your next kidney diet dish by adding zest from lemon, lime, orange or grapefruit. Zest is the colored portion of the citrus skin. It contains aromatic oils and adds loads of flavor to cooked or raw foods.
To remove the zest, use a citrus zester, paring knife or vegetable peeler. Avoid the white pith between the zest and fruit–it is bitter.

What about potassium? One tablespoon of citrus zest contains less than 10 mg potassium.
