what is the difference between creme fraiche and mexican crema?
Crème fraîche is richer and has a higher fat content, about 30%, which gives it body and thickness. It works in soups and sauces; it melts easily and won't curdle. Mexican crema is similar to crème fraîche: it's a littler runnier and tastes even more tangy. It's essentially crème fraîche with lime and salt added!
