Strawberry Rhubarb Jam
4 cups rhubarb, thinly sliced
2 T. lemon juice
4 cups of fresh strawberries, sliced
10 cups of sugar
2 packages of fruit pectin
1/2 t. butter (keeps jam from getting too foamy)
In large kettle combine all ingredients except sugar. Bring mixture to a full rolling boil. Add sugar and keep stirring till sugar is fully dissolved. Return to boil and boil for one minute. Keep stirring. Remove from the burner and skim off the foam with a spoon.
Spoon the hot jam into hot pint or half-pint canning jars. I like to pour the jam into a glass 4-cup glass measuring cup first, then pour into jars, as this makes jam easier to pour into jars. Leave 1/4 inch of space at the top. Wipe jar rims clean and screw lids on firmly. Place the jars in boiling-water canner and bring pot to a brisk boil. When water begins to boil, set timer and boil for 5 minutes. Remove the jars from canner and cool on racks. Try not to disturb jam til it is cool. It may take several hours to set.This makes about 10 half-pint jars. If you don't have an official canning pot, you can use any pot that is large enough to fully submerge the jars.
