Doesn’t DNS mean “Do Not Substitute” in pharmacy-speak? It now also applies to cooking.
When Ina Garten tells you to use creme fraiche, use it. Don’t use yogurt. (Even, well, okay, especially, greek yogurt.)

*Even if you’re trying to be “healthy.” It’s not worth it. She’s tested these recipes. She’s the expert. And a little creme fraiche won’t kill ya for cry eye!
