"You should enter The Great British Bake Off", they say.
Little do they know I can basically only bake cakes. I would barely last a week in the tent as I am rubbish at jam and scones and have pretty much zero experience with bread and pastry.
I have made jam two or three times previously and all overset to the degree they could be used as cement mortar or silicone sealant. I was convinced the thermometer lied so threw it out after my last attempt. My last attempt also burned to the bottom of the pan so I became convinced my preserving pan base wasn't thick enough either.
After moving house and discovering we had a rhubarb patch and gooseberry and blackcurrant bushes I knew it was time to conquer jam. I'm clearly not a natural, but determined nonetheless to learn. Luckily the sheer size of the rhubarb patch allows me to experiment without feeling like I've wasted too much money or precious fruit.
Armed with a different pan, new digital thermometer and a new recipe book I was ready to go!
Things I've learned about jam making in the last week:
I need a better preserving pan. I used my big Denby casserole dish this time as it has a heavy, thick base but it isn't quite tall enough for boiling jam as jam sparked EVERYWHERE. My kitchen was very sticky last week!
105C is not the "golden number" for jam setting, it's a rough guideline. I only found this out after reading "the basics" beginning section of my new jam making book, The National Trust Book of Jam. It was one of those penny dropping/light bulb moments and I suspect this could be where I've gone wrong in the past. Learning to "read" my jam will undoubtedly come with experience. For my rhubarb jam I discovered 102 - 103C was the best setting point.
Every jam is different, even when you're using the same recipe. It won't necessarily set the same even if you take it off the boil at the same temperature you used last time.
Pectin. Learn about pectin as this is what makes your jam set. Some fruits like strawberry and rhubarb are low in pectin, therefore need added pectin to help the jam set. This can be done by either using jam sugar (as opposed to granulated) and/or citrus like lemon juice. For my first batch I used jam sugar, but as I already had lemon and orange in the jam I found it made a firmer set. For subsequent batches I used half jam sugar and half granulated sugar and I felt it worked better.
For a complete jam novice I'm really pleased with my three attempts. Although the first batch is perhaps a bit too dark/over boiled, none of them are disasters. They are all edible and that's a vast improvement from previous attempts.
Batch 2 is definitely my best effort. I was initially worried it was under set but after spreading some on a scone (not baked by myself, as I said earlier, I'm crap at scones) I decided that it's actually spot on. It's incredibly tasty. There is something rather special about homemade jam.
Like the stewed rhubarb, the orange really lifts the rhubarb flavour in this jam. It's definitely a recipe I'm looking forward to perfecting over the years with my rhubarb patch.
There are also recipes for rhubarb and raspberry jam and rhubarb and strawberry jam in the National Trust Jam book which I'm keen to try later in the year. The Man and I have transplanted our young raspberry bushes and strawberry plants from our old garden so hopefully we'll have home grown raspberries and strawberries to enjoy with our home grown rhubarb in years to come.
Rhubarb, orange and ginger jam
Recipe from National Trust Book of Jam
1 kg rhubarb, washed and cut into 2cm slices.
1.1kg sugar (I used 500g jam sugar and 600g granulated sugar)
Grated zest and juice of 1 lemon
1 large orange
55g drained stem ginger in syrup
Start your prep the night before you intend to make your jam:
Layer up the chopped rhubarb, sugar and lemon zest in a large glass bowl then pour the lemon zest on top. Cover with a tea towel and leave in a cool place to soak overnight. Stir it before going to bed then again the following day before using.
Place the orange in a small saucepan and pour in enough water to almost cover it or at least half cover. Bring to the boil and simmer until the orange has softened, about an hour. Remember to turn the orange every so often to ensure it cooks evenly. Leave to cool in the pan and set aside.
The following day, wash and sterilize 4-6 glass jars and lids then place them on trays in the oven at a low heat, around 100C, while you prepare the jam.
Tip the rhubarb sugar mixture into your preserving pan. Put it on a low to medium heat and stir until the sugar has completely dissolved.
Meanwhile drain the softened orange (discarding the water) and roughly chop it up. Chuck it in a blender with the stem ginger and blend into a paste. Alternatively, chop finely. Tip this mixture into the jam pan once the sugar has dissolved.
Now bring your pan to the boil, remembering to stir every so often and remove any scum which forms at the edge of the pan. It'll take about 10 minutes to thicken and come to a setting point, around 103 - 105C.
When you think it's ready take the pan off the heat and dab a small amount of jam onto a cool saucer then set the saucer in the fridge for 5 minutes. Push your finger through the cooled jam; if the jam "wrinkles" and leaves a trail, it's ready. If not, put the pan back on the heat and boil for longer.
Take the jars out the oven and ladle jam into them, filling right to the top. Put the lids on tight (or cover with waxed discs and cellophane tops with elastic bands) and add labels, naming and dating your jam. Store your jam in a cool place and keep in the fridge once opened.
