What it is

Its colour is a working pH meter: the anthocyanins turn blue in alkali and red in acid, which is why an unacidulated pot comes out an unappetising grey-violet. German and Flemish cooks solved this centuries before chemistry explained it, by always adding apple or vinegar.

In the kitchen

Add the acid at the start, not the end. Vinegar or apple early keeps it crimson; added late it never recovers the colour.
