Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

4 cups fresh blueberries
1 ½ cups granulated sugar
¼ cup freshly squeezed lemon juice
1 package fruit pectin

Directions

Wash blueberries thoroughly, discarding any stems or leaves.
In a large pot over medium heat, combine blueberries and ¾ cup of sugar. Cook for about 5 minutes, stirring until the berries release their juices.
Add lemon juice and pectin, stirring constantly, and bring the mixture to a rolling boil.
Gradually stir in the remaining sugar and return to a rolling boil for 1 more minute.
To test readiness, place a spoonful of jam on a cold plate. If it holds its shape, it’s done.
Carefully ladle the hot jam into sterilized jars, seal tightly, and let cool before refrigerating.

FAQs

Can I use frozen blueberries?

Yes, thaw them first and drain excess liquid before cooking.

What is fruit pectin, and why is it needed?

Pectin is a natural thickener that helps jam set. Without it, the texture will be looser.

Can I make this without pectin?

Yes, but you’ll need to cook longer and rely on the fruit’s natural pectin to thicken.

How do I know when my jam is ready?

The cold plate test—if the jam holds its shape and wrinkles slightly when pushed, it’s ready.

Can I reduce the sugar in this recipe?

You can, but the jam may not set as firmly and will have a shorter shelf life.

Do I have to sterilize the jars?

Yes, sterilizing prevents bacteria growth and extends storage life.

Can I double the recipe?

Yes, but you’ll need a larger pot and may need to increase cooking time slightly.

How long will sealed jars last?

Properly canned and sealed jars can last up to 1 year in a cool, dark place.

Can I flavor the jam with herbs?

Yes, try adding fresh thyme or basil during cooking for a gourmet twist.

What can I use blueberry jam for besides toast?

It’s delicious in yogurt, over cheesecake, swirled into oatmeal, or as a glaze for meats.
