- Step 3:
- Mix the soft butter with sugar until light and airy, about 2 minutes. Toss in egg and vanilla, then beat until really fluffy.

- Step 1:
- Put blueberries, sugar, lemon juice, vanilla, and cornstarch in a pot. Simmer on low-medium heat for 30-40 minutes till it thickens up. Let it cool down completely.
- These taste amazing when eaten the same day you make them.
- Keep them in a sealed container and they'll stay good for up to 3 days.
- Your jam should be thick - if it's too loose, just cook it a bit more.
- Don't feel stuck with blueberries - try strawberry or raspberry jam for something different.
Tips from Top Bakers
