Equipment

Ingredients

  • 4½ cups crushed blueberries about 2½-3 lbs whole berries
  • 2 large limes juice and zest, see notes
  • 1 box powdered pectin 1.75 oz, like Sure-Jell or Ball Classic (or 6 Tbsp bulk)
  • 5 cups sugar

Instructions

  • Wash blueberries and crush one layer at a time using a potato masher. Measure 4½ cups crushed berries. Finely grate lime zest and squeeze juice.
  • In a large, deep stainless steel saucepan, combine crushed blueberries, lime zest, and lime juice. Whisk in pectin until dissolved. Bring to a full rolling boil over high heat and boil 1 minute, stirring constantly.
  • Add sugar all at once, stirring to dissolve. Return to a full rolling boil and boil hard for exactly 1 minute, stirring constantly. Remove from heat and skim foam.
  • Ladle hot jam into prepared jars, leaving 1/4 inch headspace. Remove air bubbles, wipe rims, center lids, and apply bands to fingertip tight.
  • Process in a boiling water bath canner for 10 minutes for half pints and pints, adjusting for altitude. Let stand in canner 5 minutes before removing to cool on a towel on the counter.

Notes

This recipe is from the Ball Blue Book. It's incredibly popular with home canners because blueberries and lime go so well together.

Fresh Lime is Best

Use fresh lime for both the zest and juice. The zest contains the aromatic oils that give lime its distinctive flavor. Bottled lime juice works for the juice portion but you'll miss the zest.

More Lime Option

Ball canning suggests just 1 lime, but I think it's much better with two.  For a stronger lime flavor, some canners use the zest and juice of 2-3 limes instead of one.

Fresh or Frozen

Frozen blueberries work just as well as fresh. Thaw first and include any juice that accumulates.

Altitude Adjustments

  • 0 to 6,000 feet: 10 minutes
  • Above 6,000 feet: 15 minutes
