I use the recipe that comes in the box. It's what my Grandma made and it's what my Mother-in-law makes. It's quick and easy and tastes fabulous! From start to finish I can make a batch of jam in 30 minutes.
Strawberry Freezer Jam1 1.75 oz Pink box Sure Jell Premium Fruit Pectin
4 pints of strawberries (1 big double container is enough for 1 batch) - 4 cups crushed/chopped
3 cups of sugar
1 cup water
I use the little 1/2 pint canning jars and I fill 8 per batch. You can use plastic containers too. Wash your jars/containers.
Rinse the berries.
Top and mash or chop. I like to use my ninja to chop them. It takes about 2 sec to get them to the consistency that I like.
I chop them in 4 batches and transfer them to a large batter bowl with measurements on the side so I can check to see that I have 4 cups of fruit. If your ratio's are off sometimes it won't set up right.
In a large saucepan combine the 3 cups of sugar, the pectin, and 1 cup of water. Stir to combine. Use a large saucepan because when the mixture comes to a boil it will expand and you don't want it to boil over.
Turn on your burner to medium high heat and stir until the mixture reaches a boil. You know you are there when the mixture is transparent in color and even when you are stirring it continues to boil. Cook at a full boil for 1 minute.
Pour the hot pectin mixture directly into the berries and stir for 1 minute until it is thoroughly incorporated.
Pour the jam into your containers. Be sure to leave about 1/2" of room at the top to allow for expansion during freezing. Put on the lids and let set at room temperature for a full 24 hours.
Then freeze for up to a year or refrigerate and enjoy!
