Green tomato soup calls for creme fraiche. I cannot have creme fraiche. If I add heavy creme will it be ok?

Question

I want to make green tomato soup but the recipe I have calls for creme fraiche. I cannot get creme fraiche. Will using heavy cream as a substitute smooth out the sourness of the green tomatoes and still be pleasant tasting? I prefer a little sweet to tart tasting anyway.

Answer 1

If you add only heavy creme the final result will be more smooth and a little bit sweeter (even though green tomatoes are very sour to taste). If you have access to a white yogurt (non sweetened) or greek yogurt you can add that to the soup, maybe by adding it gradually and correcting with cream if the taste degenerates.

Answer 2

You can easily make your own craime fraiche with heavy cream and a couple of tablespoons of live culture buttermilk. Just let it sit in a warm place overnight and it will be ready the next morning.
