Maggie Beer is one of my favourite Aussie cooks and living in the Barossa she uses a lot of verjuice. But where do you find the stuff? While it is readily available in Europe, it can be a bit hard to find around these parts. If you have access to freshly grown grapes, here's how to make your own.If they are currently in season, freeze them until you need to make the verjuice! The grapes here are the green variety used in sultana production. whatever you use the final result should be tart not sweet.
