Ingredients
Method
- Rinse blueberries thoroughly and remove any stems or damaged berries.
- In a large, heavy-bottomed pot, combine blueberries, sugar, and lemon juice. Stir gently to coat the berries.
- Bring the mixture to a boil over medium-high heat, stirring frequently to prevent sticking or scorching.
- Once boiling, reduce heat to medium-low and simmer for about 20-25 minutes, stirring occasionally. The mixture will thicken as water evaporates.
- Test jam readiness by placing a small amount on a chilled plate. If it wrinkles when pushed with your finger after 30 seconds, it's ready.
- Remove from heat and stir in vanilla extract if using.
- Skim off any foam that has formed on the surface.
- Ladle hot jam into sterilized jars, leaving 1/4-inch headspace.
- Wipe jar rims clean, seal with lids and bands, and process in a water bath for 10 minutes (optional for longer storage).
