Strip from their stalks some fine ripe black-cluster grapes, and stir them with a wooden spoon over a gentle fire until all have burst, and the juice flows freely from them; strain it off without pressure, and pass it through a jelly-bag, or through a twice-folded muslin; weigh and then bo3 it rapidly for twenty minutes; draw it from the fire, stir in it till dissolved, fourteen ounces of good sugar, roughly powdered, to each pound of juice, and boil the jelly quickly for fifteen minutes longer, keeping it constantly stirred, and perfectly well skimmed. It will be very clear, and of a beautiful pale rose-colour.
Juice of black-cluster grapes: 20 minutes. To each pound of juice, 14 ozs. good sugar: 15 minutes.
We have proved this jelly only with the kind of grape which we have named, but there is little doubt that fine purple grapes of any sort would answer for it well.
