raspberry jam - remove seeds, add more berries?
I made a couple batches of black raspberry jam from "wild" berries in my back yard. It's pretty seedy, but otherwise great! I have a lot more berries... and a cone seive and a food mill so I'd like to try a 'less seeds' or seedless batch.
The recipe called for 6 cups of berries, but if I remove seeds the volume is much less. Do I need to add more berries to make up for the lost volume?
