Method

  • step 1

    Pare the zest from the lemons with a peeler, then juice them, keeping the juice, shells and any pips. Tie the shells and pips into a muslin bag. Put the marrow into a preserving pan with 2 tbsp of the lemon juice, then cook on a medium heat, stirring often, until the pieces are turning translucent and soft but not mushy. Bubble off any juices before stirring in the sugar, the rest of the juice, the zest, ginger and the muslin bag. Stir until the sugar dissolves.

  • step 2

    Bring to the boil, then simmer for about 10-15 mins or until the marrow has softened completely and the jam has reached setting point (see Tips, below). Pot the jam into warm jars (see below). The flavour of the jam will mature and intensify over the next few months, so tuck it away in a dark, cool place.

STERILISING JARS

To sterilise jars, wash thoroughly in hot soapy water, then dry in a low oven; or run them through the dishwasher. Pot the jam while the jars are still warm. Will keep up to a year.

KNOW-HOW

To test for setting point, put a saucer into the freezer well before you start boiling. Spoon a little of the jam onto the saucer. Once cool, push it with your finger. If the jam wrinkles, it's ready.

The zest needs a lot more cooking than 10-15 mins - I wish I’d read these comments first ! Cook for longer !

Did take a fair bit of boiling but as long as you test for the setting point should be fine. It turned out very good, so tasty, especially on toast, think it would be nice over vanilla ice cream too.

I made this today as I love marrow+ginger jam that my dad used to make! I measured everything accurately but it was still very very runny and watery after almost three hours. So I took a lot of the liquid out and even added some pectin that I had in a bottle (although I did use sugar with pectin).…

So far so good, tastes lovely bubbling away. I’ve added extra ginger as I felt it needed extra zing and I cut the sugar a little. I would say 10-15 minutes boiling is a massive understatement, more like 2-3 hours!

question

Hi, thanks for your question. Ideally weigh after peeling and deseeding. We hope this helps. Best wishes, BBC Good Food Team.
