Old-Fashioned Blueberry Jam

Directions

1. 1
   In a Dutch oven, bring blueberries and water to a boil; mash and stir for 5 minutes. Add sugar and honey; boil gently, uncovered, over medium heat for 30 minutes, stirring frequently.
2. 2
   To test for doneness: Remove from heat; spoon about 1 tablespoon of hot jam onto a chilled plate and set plate in freezer until the jam has cooled to room temperature, 1-2 minutes. When the cooled jam holds its shape when mounded with a spoon, the jam has reached its desired thickness. If necessary, return to heat and repeat test after additional cooking.
3. 3
   Skim off any foam. Carefully ladle hot mixture into hot half-pint jars, leaving 1/4-in. of headspace. Remove air bubbles; wipe rims and adjust lids. Process for 10 minutes in boiling-water canner.
