This is my own rendition for Ranch Dressing that helps me when I diet. It's a recipe developed for my own tastes, but I find that it takes the place of the tangy RD when I want it. You might want to use the following seasonings adjust, or taste as you go.
For almost one cup - I have no idea what the cal count is.... but lower than the usual.
1/2 Trader Joe's or good plain non fat yogurt, drained well
3 T non fat or light sour cream
1 T mayonaise - light or use the real thing - 90 cal per Tablespoon for real mayo
1/3 C lowfat buttermilk - makes it better but if you leave it out, use more of the vinegar and a little lowfat milk
1 T garlic powder
1 tsp onion powder
1 T celery salt
1/4 tsp dill weed
Fresh parsley chopped fine - sometimes I leave this out if I am making large batch and then I will add parsley to a small serving for small snack time.
I also do this if I don't have fresh buttermilk. I add a splash of Citrus Champagne Vinegar. "O" brand.
I mix and let it sit for a couple of hours.
Drain the yogurt it will be thicker
Ranch Dressing is about the buttermilk, the garlic powder and the celery salt, so you want those flavors to come through over the dill. And if I don't have any on hand, I still splash it with the champage vinegar, because I love the tang.
I can give up sugar, I can give up wine or beer but I can't give up salt.
Drink lots of water too!
