I'd never made jam w/o my mom until today, and this was almost as yummy. (Almost only because it doesn't have real sugar, you really can't tell!)
5 C fresh strawberries, blended
1 C splenda (or less + some real sugar)
1-2 Tbs lemon juice + 1 tsp lemon zest
1 pkg pectin (I used Sure-Jell)
In a bowl stir together strawberries, lemon, and splenda/sugar, let sit 15 min. Then add pectin, stir 3 min, let sit 5 min. Stir again, pour into containers (leaving room at the top for expansion), freeze.
