Once baked it’s garnished with candied fruit, pine nuts and a sprinkle of sugar.
There are also variation which involve cream, marzipan or angel hair (caramelized pumpkin) filling or you could go all posh gourmet and order one from of the most bespoke bakeries of Barcelona at Bubo where the Coca de Sant Joan is given a major twist (alas, no such esoteric takes in Tarragona yet).
