What sort of cream would you put in coffee? I mean, are we talking like 50% fat or 20% fat?
I think the names and designations for cream in the US differ from those in the UK and the rest of Europe, but when I say cream, I mean what is referred to in the US as "heavy cream" or "heavy whipping cream." It's 36%-40% fat. I use this at home. In restaurants and coffee shops the highest fat content available to put in coffee is usually "half and half" which is a mixture of whole milk and heavy cream. It is around 18% fat or a bit less. We also use this at home.
I don't do frothy milk coffee drinks so I don't know what froths better. My standard coffee at home is a strong dark roast, with a splash of heavy cream, no sugar. If I'm out it's the same, but with a bit more half and half to make up for the lower fat content.
