Homemade Lemon Jam
A bold sweet-sharp lemon preserve with tender citrus slices and a naturally glossy, syrupy set.
01 β THE STORY
Behind the plate
This whole-fruit lemon jam sits between a jam and a fine-cut marmalade. Thinly sliced lemon provides juice, pith and peel, creating a preserve with concentrated citrus perfume and a pleasant grown-up bitterness.
Softening the slices in water before adding sugar is the important control point. Once the sugar enters the pan, the mixture reduces quickly into a bright, spoonable preserve intended for refrigerated storage.
03 β THE METHOD
Cook step by step
- 01
Wash the jars and lids thoroughly and keep the jars warm. Unless you follow a separately tested canning method, store the finished lemon jam in the refrigerator.
- 02
Place the thinly sliced lemons and water in a wide, heavy-based pan. Bring to the boil, then simmer until the peel and pith are completely tender.
- 03
Add the sugar and stir over medium heat until every crystal has dissolved before allowing the mixture to boil strongly.
- 04
Cook at a controlled boil, stirring frequently as the syrup thickens and the lemon slices become translucent.
- 05
Test the set by placing a small spoonful on a chilled plate. Leave it briefly, then push it with a fingertip; a light wrinkle means it is ready.
- 06
Remove from the heat and carefully fill the warm jars. Wipe the rims, close with clean lids, cool and refrigerate.
04 β FROM THE PASS
Chef's notes
- Slice the lemons evenly so every piece softens at the same rate, and remove all seeds because they become unpleasantly hard.
- If the peel is not fully tender before the sugar is added, it is unlikely to soften properly later.
- Lemon jam sets more firmly as it cools, so avoid reducing it to a stiff paste in the pan.
- A lid drawing down during cooling does not by itself prove the product is safely canned. Pantry storage requires a tested recipe and complete altitude-adjusted water-bath process.
- Keep refrigerated and use within 3 weeks. Discard if you see mould, fermentation, leakage or smell anything unusual.
