Can i use creme fraiche instead of soured cream in this recipe?
You certainly can. Creme Fraiche is essentially fancy french sour cream, it has a lower butterfat content and also has bacterial culture (like yogurt) but is made with essentially the same process. It works wonderfully for desserts and many pastry chefs will choose it consistently over sour cream (we’re pretty much all snobs 🙂 If you are worried about it you can make your own sour cream very easily (if you have cream that is) add about a teaspoon of acid – lemon juice or vinegar work very well – to a cup of cream and stir until it thickens to a sour creamy consistency. This takes a moment and then happens very fast… it’s actually pretty cool to see.
