Blueberry Lime Jam

Our neighbor introduced us to this incredible recipe. A hint of lime brings out the blueberry flavor in this highly addictive jam. For the last three years we've made at least two - and sometimes as many as six - batches of this jam when blueberries are in season.

Prep: 15 min
Cook: 15 min
Total: 30 min (2 hours with canning time)
Yields three 16 ounce jars

Jam
4 ½ cup blueberries (about 1 ½ pounds)
Wash blueberries and remove all stems or rotten berries. Place as many berries as will fit in a single layer in a large saucepan or stock pot and crush with a potato masher. Add remaining berries and crush.
1 package powdered pectin (1.75 ounces)
Add powdered pectin to pan and stir to combine.
While stirring frequently, bring crushed berries to a boil over medium-high heat, about 5 minutes.
5 cups sugar (2 pounds 3 ounces)
Pour sugar into pan and stir until dissolved.
⅓ cup lime juice
1 tablespoon grated lime peel
Add lime juice and lime peel and stir to combine.
Bring entire mixture to a rolling boil while stirring constantly to prevent the jam from burning or sticking. Once jam reaches a rolling boil, set a kitchen timer for 1 minute. When timer sounds, remove from heat.
Canning and Preserving Method
Follow home canning and preserving instructions. Carefully pour jam into prepared jars, leaving 1/4-inch headspace. Clean rim of jar with a damp, clean cloth and position two-piece lid.
Process jam in a boiling-water canner for 15 minutes. Remove and let rest for at least 12 hours before testing seals.
If a jar has not sealed properly, you can re-can and reprocess it within 24 hours, or you can apply the refrigerator method for that jar(s).
Canned and preserved jam will last for up to 1 year. Once opened, preserved jam will keep for two or more weeks in the refrigerator.
Refrigerator Method
Alternatively, you can skip the canning and preserving and simple refrigerate the jars if you plan to consume the jam immediately. If you find that you have too much, give a jar or containers worth to a friend. Refrigerated jam should be good for at least two weeks. Use your common sense to determine if it has spoiled, but more likely than not you'll have eaten it all long before that point.
