Yes, you can use crème fraîche instead of double cream, but it will alter the flavor and texture of the dish. Crème fraîche is tangier and thicker than double cream, which can add a unique taste to your recipe. However, it won't whip up like double cream, so it's best used in cooking or as a topping rather than in recipes that require whipped cream. Adjustments to other ingredients may be necessary to balance the acidity.
custard
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.
It means the very best. (literally cream of the cream)
cream
creme diplomat is made by folding whipped cream into cold creme patissiere (pastry cream). It has the sweet, custardy taste of the creme patissiere but is lighter, both in texture and flavour.
Literally translated: cream of the cream. It is a French colloquialism stemming from milk. Cream rises to the top in unpasturized milk and is considered the best part of the milk. The top layer of cream is skimmed off first, leaving some cream in the milk. The rest of the cream is considered a little lower quality, since the cream will have other parts of the milk in it. That top layer is the cream of the cream, or creme de la creme -- the best of the best. cream, the best of the best!
wrong spelling...it is creme fraiche. Got my answer from wikipedia.
Fresh Cream
"Nata" or "creme"
A suitable replacement for creme fraiche in recipes is sour cream, Greek yogurt, or a mixture of heavy cream and buttermilk.
