Also - for a creamy style dressing:
Take some plain kifer and sweeten it slightly with honey (or agave nectar) season with finely minced thyme, parsley, dill, basil and a little onion powder, garlic powder and salt. RANCH DRESSING! (My family can't tell the difference - and they aren't on the diet)
Or sometimes I do this for a dinner with guests:
Kifer, again sweetened with caramelized onion, salt and thyme
Kifer, the best creamy blue cheese you can find (most roqueforts are sheep's milk - and it's only for a "treat") a blob of sour cream and a blob of mayo (home-made) and lemon juice. Mmmmm!!!
