So what makes a conserve different than a jam or jelly? The addition of nuts. It is normally very thick and chunky. Not to mention delicious.
7 pound basket of grapes (take out seeds)
4 pounds sugar
1 pound seeded raisins
$.25 worth of walnut meats (more the merrier)*
Cook until thick. Burns very quickly. Sweeten more if necessary.
*According to prices that were advertised in The Daily Record [Morris County New Jersey], December 15-25, 1910, one pound of walnuts was $.18. I am thinking that this would require 1 lb to 1 1/2 lbs of walnuts.
