Recipe from Double the Deliciousness
1 1/4 cup mashed strawberries
2 cups finely chopped peaches
1/4 cup lemon juice
1 (1.75 oz) box Pectin
4 1/2 cups sugar
1 cup light corn syrup
Wash strawberries, remove, stem and mash them with a potato masher until coarse. You still want a few chunks in there. Wash and peel peaches. Chop with a knife into small chunks. Add the peaches to the strawberries and stir to combine.
Add the lemon juice and stir. Sprinkle box of pectin over fruit and then stir really well. Let fruit mixture sit for 30 minutes, stirring every 5 minutes or so.
Pour in the corn syrup and mix well. Gradually pour in the sugar and stir until sugar is dissolved and it is no longer grainy. You may want a second set of hand to help you with this part. It takes a little bit of time & my arm felt like it was about to fall off by the time it was ready! Just a heads up...but it's worth it!
Pour jam into freezable containers, 1-2 cups size, leaving about 1/2 inch room at top to allow for expansion while in the freezer.
Let sit on the counter for 24 hours and then either refrigerate & use within 3 weeks or freeze for us to 1 year. Makes about 7 cups.
