Step‑by‑Step Instructions for Mary Berry Blackcurrant Jam Recipe

Step 1: Wash and Prep the Berries
Rinse blackcurrants, removing any stems or leaves. If frozen, fully thaw before using.
Step 2: Simmer the Fruit
Combine blackcurrants and water in a heavy‑bottomed pan, simmering for 10–15 minutes until soft.
Step 3: Add Sugar and Lemon Juice
Add sugar and lemon juice; stir on low until sugar is fully dissolved.
Step 4: Boil to Setting Point
Bring to a rolling boil, stirring occasionally. Cook for around 10 minutes, then test on a chilled plate; the jam should wrinkle slightly when ready.
