prepared fruit (buy about 1 qt. fully ripe strawberries)
sugar, measured into separate bowl
fresh lemon juice
Rinse clean plastic containers and lids with boiling water. Dry thoroughly.
Stem and crush strawberries thoroughly, one layer at a time. Measure exactly 2 cups prepared fruit into large bowl. Stir in sugar. Let stand 10 min., stirring occasionally.
Mix pectin and lemon juice in small bowl. Add to strawberry mixture; stir 3 min. or until sugar is dissolved and no longer grainy. (A few sugar crystals may remain.)
Fill all containers immediately to within 1/2 inch of tops. Wipe off top edges of containers; immediately cover with lids. Let stand at room temperature 24 hours. Jam is now ready to use. Refrigerate up to 3 weeks or freeze up to 1 year. Thaw in refrigerator.
