For many years I have wondered how medieval recipes could call for verjuice as a year-round pantry staple. The season for immature grapes from which you can get any amount of juice is maybe 3 weeks or so, right about now. Moreover, and far more importantly, once you squeeze them, they begin to oxidize and if you try to keep it any length of time, they inevitably grow mold. This happens in the fridge too. So last week I was at Acquiesce winery in Lodi, and they were thinning the vines and I asked if I could take some cut clusters. Two big shopping bags, nearly enough to fill my huge stockpot. Crushed by hand and left - here's the key - to FERMENT. There's enough sugar in them to maybe get 5-10 percent alcohol. It smells magnificent. And is wonderfully sour. So I am expecting, as often happens with historical cooking experiments, that if you really do exactly what would have been done in the past, it should work. In this case the alcohol should make it shelf stable. In the meantime there are some recipes in the Livre fort excellent de cuysine I simply must try. I should be done with my half of the translation by the end of the week. To be published by Prospect Books.
