Grate the carrots, no need to peel if they are in decent condition.
Put a small handful of grated carrot aside
Simmer the remaining carrots in a little water, with the lid on, until very soft.
Then standing over the pan, remove the lid and hard boil until the remaining water is mostly gone.
Tip in the sugar, the reserved carrot and the zest and juice of the lemon.
Simmer until most of the moisture has gone. Keep watching it!
While the jam is simmering, sort your jam jar(s) out. If you haven’t already, wash it/them, and pop them in a low oven to sterilise them. Some people use jars fresh from the dishwasher. Whatever you do, they need to be very clean, and dry.Any water in the jars allows a sugar syrup to develop, and over time, that may well grow mould, spoiling your lovely jam. And they need to be scrupulously clean so your jam will keep well, there must be no germs, bacteria or mould spores at all in the jars.And don’t forget the lids. If you are not using lids, cover the jars with cellophane circles and elastic bands. Or use circles cut from cereal box inners and perhaps a pretty ribbon. A little gingham fabric looks fabulous. Anything that will keep the jam clean and dry will do the job.
Stir well. Leave to cool for about 10 minutes, stirring now and again
Put your jar(s) on a heatproof surface and carefully ladle in the jam. Be careful, splashes will burn you badly at this temperature. A jam funnel is helpful for this
I usually put a very clean tea towel over the filled jar(s) until they are just warm and only then put the lid on. The tea towel is to keep any mould spores in the air, off the surface of the jam.I do this so that the steam from the cooling jam doesn't create a sugar syrup on the top, an ideal pool for undesirable things to grow in.Others have recommended putting the lids on straight away and turning the jars upside down for a few seconds.
Notes
I only had 200g carrots left on the meal plan, which makes ¾ jar. To make 1 full jar, use 300g carrots and 220g sugar. Continue with a whole lemon, or use 1.5 if you have it. Nutrition per tblspThis is just as nice using swede. Bet you wouldn't be able to tell what it was!
