Making homemade jellies and jams is one of my favorite thing to do when fresh fruit comes into season. Strawberries wild and cultivated are in season here and I just could not resist a large sale that featured strawberries at a local market. Strawberry Jam is one of the easiest jams to make and is almost fool-proof.
I would love to have a strawberry bed in the near future but for now I have bought mine. So in about 1 hour 30 minutes, I made enough jam to feed my family for the rest of the year. The total cost for making Strawberry Jam was about 8$ compared to 17$ dollars if you pay 3 dollars a jar for store-bought Jam.I am hoping that next time I can drop the cost to 3$ dollars when I can raise my own berries.
Following the Ball Blue Book canning guide you will need 2 quarts or 8 cups crushed clean fresh strawberries. I bought 5 pounds of strawberries and used about 3 pounds to get 8 cups of crushed strawberries. 7 cups of sugar, 1/4 cup lemon juice and 6 Tablespoons Ball Classic Pectin. This is one whole jar of powdered pectin. 1 to 2 tablespoons butter if needed to reduce foaming.
You will need 8 half pint jars ( we call them jelly jars) with lids and rings I always get two extra ready also. A boiling water canner with enough boiling water to cover the tops of you jars with 1 to 2 inches of water.You will need a potato masher to make the crushed fruit, a jar lifter, funnel and a ladle. One large dutch oven or stock pot for cooking the jam in. I like to wear rubber gloves to protect my hands from the boiling hot jam but you can skip it if you are careful.
After washing jars lids and rings, sterilize the jars either in the microwave or in the boiling water of the canner. I boil my lids and rings separately in a small sauce pan that I keep very hot until ready to us. Remove from sterile jars from canner or microwave and place on a towel to cool and dry.
In large stock pot add the 2 quarts of smashed berries, lemon juice and classic pectin mix together well. Bring to a boil, stirring to keep from scorching. Add sugar to pot and stir until sugar dissolved. Return to a rolling boil, one that will not stop when stirred. Boil one minute stirring constantly. Remove from heat add one teaspoon of butter if jam is foamy on top. Mix in well and skim top of Jam to remove foamy skin. Ladle hot jam into clean jars leaving about 1/4 of inch of headspace.Be careful to not to burn yourself on hot syrup. Clean top rim of jar to remove any leftover fruit or juice adding lid and adjust ring. Process 10 minutes in boiling water canner. Remove from hot water and let completely cool check rings and tighten if needed and store for up to one year.
In the end I finished the morning with 9 half pint jars of jam and still had a few strawberries left over for strawberry rhubarb jam also. I grow rhubarb so I made a small batch of Jam with the leftover berries and three stalks of rhubarb.They all tasted great and will keep us thinking of summer all winter long.
