What are the peanut butter makers doing messing around with berries? Making jam, that's what – but we don't call it jam because it hasn't got enough sugar. What it has got though, is boysenberries! Glen, from Tasman Bay Berries, grows boysenberries. Lots of boysenberries. In fact, Nelson is the boysenberry centre of the Universe. Glensfarm is just down the road from Pic's Peanut Butter World in the heart of Stoke. We are super lucky and get to eat them fresh in December; it's a Kiwi tradition of packing ice cream tubs full of juicy pick-your-own berries. But the rest of the world hardly ever sees them, which is a pity as they are extraordinarily nutritious and boysenberries go really well with peanut butter. What is in Pic's Boysenberry jelly? Boysenberry puree (grown in Nelson) 49%, Boysenberry concentrate 3%, cane sugar, lemon juice concentrate, gelling agent (pectin).
