Blueberry-Apple Jam With Cinnamon - cooking recipe

Ingredients

1 apple
1 lemon
1 pt. blueberries
2 1/4 c. sugar
1/4 tsp. ground cinnamon

Preparation

Peel apple and grate into a large saucepan.
Grate yellow zest from the lemon into pan and squeeze in juice.
Add blueberries and sugar.
Lightly crush berries.
Bring to a simmer over medium-high heat, stirring constantly.
Skim any foam that rises to the surface while cooking.
Reduce heat and simmer until jam reaches the sheeting stage (220\u00b0), about 35 minutes.
To test, dip a spoon into the jam and hold over the pan; two drops that start at opposite sides of the spoon should meet before they fall off. Remove from heat and stir in cinnamon.
Cool to room temperature and pour into jars.
Chill.
Store in the refrigerator.
