Crème fraîche weighs 230 grams per cup, close to sour cream's density, and the two are genuinely similar products — both are cultured cream — but crème fraîche is made with a higher fat content and a different, milder bacterial culture, giving it a smoother, less tangy flavor and, critically, the ability to be boiled without curdling, unlike sour cream.
That heat stability is crème fraîche's defining practical advantage over sour cream in cooking — sour cream's lower fat content and different protein structure make it prone to curdling or breaking when added to a hot sauce, while crème fraîche's higher fat content lets it be stirred directly into a simmering pan sauce or soup and stay smooth.
Crème fraîche has deep roots in French cooking, used both as a finishing touch (a dollop on a savory tart or soup) and as a genuine cooking ingredient stirred into sauces for richness — a dual role that reflects its more heat-stable structure compared to sour cream, which in French and other European kitchens is more often treated as a cold condiment than a cooking ingredient.
It's sometimes used to finish a soup just before serving, swirled on top for both visual presentation and a cooling, tangy contrast to a hot, richly flavored broth.
A dollop of crème fraîche is a classic topping for a bowl of fresh berries or a slice of fruit tart in French cooking, valued for its mild tang balancing the fruit's sweetness without dairy milk's blandness or sour cream's sharper edge.
It's also stirred into scrambled eggs off the heat for extra richness and a silkier texture, a technique some chefs prefer over adding butter or cream directly during cooking.

Frequently asked questions
Is crème fraîche the same as sour cream?
They're closely related cultured cream products, but crème fraîche has a higher fat content and a milder culture, giving it a smoother, less tangy flavor and — importantly — the ability to be boiled without curdling, which sour cream can't reliably do.
Why can crème fraîche be added to a hot sauce without curdling?
Its higher fat content stabilizes it under heat in a way sour cream's lower fat and different protein structure can't match, letting it be stirred directly into a simmering dish and stay smooth rather than breaking or curdling.
Can sour cream substitute for crème fraîche?
In cold applications (a dollop, a dip), yes, reasonably well — but in a hot sauce or soup where crème fraîche is meant to be simmered in, sour cream is genuinely more likely to curdle, so the substitution works better cold than hot.
Is crème fraîche sweet or tangy?
It's mild and only lightly tangy — noticeably less sharp than sour cream, with a subtler, more rounded flavor that's part of why it's often used as a finishing touch rather than a strongly flavored ingredient in its own right.
Can crème fraîche be made at home?
Yes — combining heavy cream with a small amount of buttermilk (which provides the live cultures) and letting it sit at room temperature for 12-24 hours produces a reasonable homemade approximation, though it won't precisely match the exact culture strains used commercially.
