To all the non-Americans out there who (like me!) were ever wondering what this mysterious ingredient is that they keep seeing in lots of American recipes. Simple enough, apparently. American "half-and-half" is a commercially prepared dairy product that is half whole milk and half cream. That's single cream, to all of Brits. If a recipe calls for one cup of half-and-half, use 1/2 cup whole milk and 1/2 cup single cream
And if you are wondering why I am posting this now, check this space shortly for some delicious American recipes? to come! You may come across the Half and Half being used there, so stock up with some single cream.. You know, you want to!
