I live in the UK and want to buy some black cocoa powder, also known as black onyx cocoa powder. This is a type of cocoa powder that has been alkalized more than standard cocoa powder. As a result, it is much darker than normal cocoa powder and tastes different. It is what is used to make Oreo cookies.
The only places I can find that sell it are in the USA, and they won't ship internationally.
Is it available in the UK? Surely it must be?
