Hurry! Just today the sour, sweet and spicy treats will be on sale at the top of the cable cars. 

It is a very particular fruit that packs an explosive flavor punch:

You’ll be welcomed with the tangyness, then relieved with some sweetness, and be left wanting more with a slighly spicy aftertaste (little like Paprika).

Due to these characteristics, their jams are not overly-sweet and have interesting spicy notes- comparable to a chutney. 

Buy a bag or a jar of jam  and see what the craze is all about!
