I wouldn't suggest using buttermilk in carrot soup. It would give your soup a soured flavor.
You can substitute buttermilk as a nice, tasty alternative. So is mayonnaise.
Yes, you can use buttermilk with baking powder.
you wont get the same taste from using double cream instead of sour cream and the consistency might be a bit off.
Yes you can but it is easy to make creme Fraiche. Take heavy cream preferably the ultra pasteurized kind as it has a lower bacterial count than the normal stuff. ( the normal stuff whipps better though and is not unhealthy in any way other than the high fat. Add to the cream some buttermilk. Let the cream stand overnight. When you get up the cream should have set up into cream fraiche. Use sapringly as it is about 1/3 fat.
Buttermilk has a different acidity than whole milk. If used in a cake mix that calls for whole or 2% milk, a teaspoon of baking soda should be added to balance the acid in the buttermilk.
I would use a light dip. such as buttermilk ranch.
why not it is same thing just not as fatty
You can use both, but for the better texture and better taste use double cream Hope this helped
No, they are too different.
no
You can use Sour Cream of Mayonnaise as a substitute of yogurt.
