Strawberry Jam - cooking recipe

Ingredients

2 qt. strawberries (4 1/2 c.)
1 box Sure-Jell
7 c. sugar

Preparation

Clean and wash fully ripe fruit.
Mix Sure-Jell with fruit in 6 or 8-quart saucepan.
Place over high heat and stir until mixture comes to a hard boil.
At once add sugar.
Bring to a full, rolling boil that cannot be stirred down.
Boil hard one minute, stirring constantly.
Remove from heat and skim off foam. Stir and skim five minutes to cool slightly and prevent floating fruit.
