Step 1

Add the blackberries, sugar, lemon juice, lemon zest, vanilla seeds, vanilla pod, and salt to a large saucepan.

Step 2

Stir well and let the mixture sit for about 20–30 minutes to help the berries release their juices.

Step 3

Place the saucepan over medium heat and bring to a gentle boil.

Step 4

Cook, stirring often, for 18–25 minutes until the jam thickens and becomes glossy.

Step 5

Mash the berries lightly with a spoon or potato masher, leaving some texture for a rustic French-style jam.

Step 6

If using butter, stir it in during the last 2 minutes.

Step 7

Test for doneness by placing a small spoonful on a cold plate; if it thickens and wrinkles slightly when pushed, it is ready.

Step 8

Remove the vanilla pod.

Step 9

Pour the hot jam into a clean glass jar. Let cool, then refrigerate.
