Jam making. Ah, it can be a contrary business. As you can buy almost any type of jam you like from small supermarkets or even corner shops, it can seem a bit bonkers to get all worked up trying to anticipate whether the setting point has been achieved and dealing with gigantic vats of boiling fruit and sugar.
But there is something so old English, so country housewife, so simple-life about the idea of making my own, that draws me in every summer. There is a ton of information out there on how to do it at home both online and in good old fashioned cookery books, and I do recommend reading up on it so you are appraised of the literature and can react to your instincts as you make your own as I find following methods slavishly has seen me turn out too many jars of road tar rather than beautifully softly set glistening jars of jam. M
y Strawberry, Lime & Vanilla Jam uses half the sugar that trad recipes do so all the flavours shine brightly through the sweetness and if you have only ever tasted commercially produced jams before, you’ll be blown away about how the fruitiness is front and centre with the sugar very much in the background.
A bit of a breakthrough came when I was reading the very old The Women’s Institute Book Of Preserves & Pickles which talked about how you need the fruit to evaporate off much of their liquid content before the setting point is achieved. Interesting. It would seem evaporating the water to leave the fruit pulp and sugar brings about a set, not achieving the elusive 104-105˚C on a sugar thermometer that I have struggled to reach.
Tell me I’m not the only one! The one time I did get it to temp, it took so long that I should have known the chewy, thick, road tar in the pan before me was not going to magically cool to a luxurious soft set. And that was with my top quality Thermapen thermometer.
When you stand by the pot, stir frequently and watch the pan of bubbling fruit before you, you can almost see when the set point has been reached. It will reduce in volume quite a bit and the best marker for me is the “flake” test – stir the jam with your spoon or spatula and let it run off into the pan. It is ready when it falls off in “flakes” – kind of like porridge oats.
When you’ve seen it once, you’ll know exactly what I mean. And it is always best to underdo a jam, allow it to cool in the prepared jars, then give them a jiggle and see if the set is what you want it to be. If it is too runny, scoop them all back into the pan and try again following the same advice and guidelines. It may take a few batches to make (so don’t choose a recipe with 5lbs of fruit in for your first go!) but once you’ve got the knack, there will be no end to your passion for preserving 😀
