I'm gonna try that recipe. I find yogurt to be a healthier replacement to sour cream, and over time I can hardly tell the difference when mixed in sauces and dressings.
I have this issue with my wifey about the garlic. Recipes like this and humus recipes that call for raw garlic. I love garlic but it kicks my ass when it's raw. I like to sweat it a bit in olive oil for just a minute or two, just to get the raw heat out of it. She likes it full strength uncooked and I find it too harsh that way. I'm very sensitive.
