Blueberry Jam

From BIG MILL BED AND BREAKFAST

Directions

Ingredients

4 pints fresh blueberries

Zest and juice of 2 lemons

7 cups sugar

½ teaspoon butter, to reduce foaming (optional)

2 pouches liquid fruit pectin (6 ounces total)

 

Step-by-step
Fresh-picked, blueberries, with some of the berries not totally ripe make the best jam. So if you are able to pick your own and make the jam immediately, it will be worth it. My blueberries are growing right outside my kitchen window, so they are very fresh.

Put half of the berries in an enamel or stainless cooking pot and crush the berries, making juice. Stir in the remaining berries, the lemon zest and lemon juice. Add the sugar and butter and bring to a full rolling boil that cannot be stirred down. Pay careful attention to the pot. It will boil over in a heartbeat and you don’t know what a mess is until you boil over blueberry jam.

While the berries are seriously boiling, quickly add the fruit pectin and stir for exactly one minute. Remove from heat and put in sterilized jars, following canning directions.

 

Yield
10 half pints plus a wee jar for tasting.
