Kefir drink and Kefir cheese are very healthy, containing good bacteria (Probiotics). I believe that it is one of the keys to the healthy Middle Eastern diet.
You can buy Kefir at health food stores like Henry’s or Trader Joes, and at any Middle Eastern market, like Fairuz Market in Rancho Cucamonga.
Mix the Kefir cheese with Olive Oil and even raw egg yellows, and use as a salad dressing or raw vegetable dip in place of fake store bought ranch dressing.
