Sour Cream, Crema, Crème Fraîche: What’s the Difference?

The headline makes me think of Seinfeld: “What’s the…”  But I digress…

Sour cream, crema, and crème fraîche: these three dairy products are often used to add a cool lusciousness and body to foods like potatoes, salads, and nachos. But while all three products are made the same way—by adding friendly bacteria to heavy cream—they’re all technically different ingredients.

While we’re here, might as well address vitamin K content…

Sour cream contains:

  • 1.8 mcg of vitamin K per 100 grams – that’s 2% of the Daily Value (DV)
  • 4.1 mcg of vitamin K per 1 cup/240 grams – 5%

I couldn’t even find information on crema – every search engine thinks I misspelt “cream”.  Sigh…

Crème Fraîche, according to sources, has 0 mcg of vitamin K.

If you consume in consistent quantity and frequency, you’re fine because your blood thinner medication dose already has it taken into account.  But depending on the amount you consume and timing just before an INR test, there’s a chance you could have a conversation with your doctor about changing your dose and testing again in the near future.

Space Espresso

Aboard the ISS, astronauts are sipping their espresso through straws attached to plastic pouches, the vessels developed through a collaboration between an Italian engineering team and the coffee company Lavazza. As any snob worth their weight in beans obviously knows, a plastic pouch and a straw are NOT ideal methods for enjoying espresso. Part of what makes a great (tiny) cup is the crema that forms on the top—caused by the emulsified oils that rise to the top thanks to gravity, creating that silky light brown layer of foamy stuff above the espresso itself.

I guess someone on the ISS needs their espresso, by any beans necessary…
