Input: I've seen many recipes that use sour yogurt as a main ingredient, but I've been unable to find sour yogurt where I live, and I wonder if it's ok to use sour cream instead of sour yogurt.I know they're pretty much the same thing, but I'm not sure if it's going to change the composition/texture of the food by making this substitution. If it's not recommendable, what would be a good substitution? For example would it be better to use plain yogurt? Like the one sold at Walmart even though is a bit sweet. Thanks
Output:
Is it ok to use sour cream as substitute of sour yogurt?
