Can I substitute crème fraiche with yoghurt??

[0rangesandstrawberries]

The recipe wants 500ml of crème fraiche and I only have 350ml. So it's just a top up! I've no idea about these things. Or some other thing I may have?

It's a gratin dish. Leek and lentils

Yes fine

that sounds delicious

Okay thanks

I treat the following as almost interchangeable in recipes

Creme fraiche
Yoghurt
Soured cream
Actual cream

I make sauces using low fat Philli too

Cream is more sweet than the others.

Cream Fraiche is between sour cream and cream ....
But yes, yoghurt is a fine replacement.
