Remove strawberry stems, then crush strawberries thoroughly, one layer at a time. Crush raspberries; sieve 1/2 of the raspberries to remove seeds, if desired. Measure exactly 1-1/2 cups crushed strawberries and 1-3/4 cups crushed raspberries into large bowl. Add lemon juice; mix well.
Stir pectin into prepared fruit in bowl. Let stand 30 min., stirring every 5 min. Gradually add sugar, stirring after each addition until well blended. Stir additional 3 min. or until most of the 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.
