Onion Jam
The Recycled Cook
By Adrian Sleeman
Onion Jam
Having been given half a dozen extremely large white onions that a friend of mine grew on his allotment I originally set out to make some onion jam with them and in the process that also turned into a classic French onion soup. I will start with
the jam and do a separate blog for the soup later.
Is it technically recycling when you set out to make one thing and end up making two?
Probably not but they are both great ways to use up rather a lot of onions and they both start of the same way.
First of all you need to peel and thinly slice the onions into a large saucepan. If you use a Mandoline , as I have done, make sure to use the guard provided or risk slicing your fingers as well as the onions. I usually start off just slicing the vegetable but see the guard long before I get anywhere near my fingers.
Sweat off the onions with some cubes of unsalted butter and olive oil, I used a garlic infused oil but that is just my preference. Soften for about 15 to twenty minutes turning frequently over a low heat until the onions are soft and golden brown in colour.
Note: If making Onion soup you would then add a cup of plain flour to the onion to make a roux which would act as a thickening agent.
Once the jam is reduced and thickened you can either blitz it to a smooth consistency of if preferred leave the onion slices whole. Adjust the balance of vinegar and sugar to taste and bottle in sterilised jam jars.

These can be sterilised before use by putting in the oven for ten minutes on a moderate heat, take care when handling as glass retains heat very well.
