Thanks for your comment! Point taken about the cultures, assuming you have those starters on hand; however, yogurt starts with milk, whereas sour cream and creme fraiche start with cream.

Creme fraiche is usually higher in fat than sour cream and I think that accounts for part of the flavor/texture differences. Cultures vary from one commercial brand to next. The New England Cheesemaking Supply Company has starter cultures for creme fraiche, sour cream, yogurt, kefir and various cheeses: http://www.cheesemaking.com/cheeseculturesandmoldpowders.html

That's a good question. I think you're playing it safe by "repasteurizing" the milk. If I open a cream carton and put it to use immediately to make sour cream, I don't feel compelled to reheat it. If you're using milk from a carton that has been open for a while, I think it would be smart to heat it. Good comment!

That's a legitimate question Dan! I may have space in my life in the future to take on the project of a new garden bed, but not any time soon. I've opted for piano practice instead. :-) Liz
