Wash Blueberries thoroughly and drain excess water.
In a large sauce pan add in the Blueberries and Sugar.
Add in Lemon juice,
Heat on low to medium heat and boil until all the sugar has been absorbed.
Add in the tablespoon of Vanilla Extract and slightly stir Blueberries.
Boil until most of the Blueberries have melted and thickened. The Marmalade needs to cool off so it is best to leave it out overnight.
The following morning place in a jar and enjoy your delicious homemade Blueberry Marmalade on toasted bread along with a great cup of coffee!
