Preserve spring rhubarb in sweet soft-set jam

Make sweet soft-set rhubarb jam with tender red rhubarb stems. Make it with only three ingredients and very simple instructions.

Spring rhubarb is the earliest homegrown treat but it only lasts a short while. After spring you’ll need to wait another year to taste it again so while the stems are red you should set about making jam. Especially sweet soft-set jam that can be spooned over pancakes, desserts, ice cream, and buttered bread. This recipe will make four small jars so if you’d like more, double (or triple!) the amounts.

The jam is soft-set and perfect for spooning

Forced Rhubarb

There’s a lot to be said for early spring rhubarb. It’s more tender, redder, and has a more delicate flavour than summer rhubarb. This is even more the case if you grow or buy ‘Forced’ rhubarb. It can set you back up to £1 per stem but it’s very easy to grow yourself — it’s just rhubarb that’s been grown in the dark.

If you have a rhubarb plant in your garden, place an upended pot or bin over the plant in winter. Leave it there until early spring and then harvest the sweet red stalks as early as February. Take the covering off completely in April and don’t force the same plant two years in a row.

This soft-set preserve makes 3-4 120g jars (2-3 340g jars). I prefer using smaller jars so that the jam is used up more quickly!

Print this recipe
500g / 1 lb Early Rhubarb
450g / 2.5 cups Jam sugar (it has added Pectin)
Juice of half a Lemon

Jam jars & lids
Optional: Tattler BPA free preserving lids (see more below)
Easy-fill funnel

Step 1: Prepare the Rhubarb

Rinse the rhubarb stems in cool water and then trim the leaves and bottom of the stem. Slice the stems into 1/2″ pieces and place them in a large saucepan. Pour the sugar over the rhubarb, stir to cover all the pieces and then let sit overnight. You can leave the fruit on the counter but make sure to cover it with the pan lid.

Step 2: Boil the Jam

Overnight the sugar will have drawn the juices out of the rhubarb and the pieces will look slightly shriveled. Pulling the juice out of the ‘fruit’ will help keep the pieces from falling apart completely in the jam making process.

Now place the pan on your hob and bring to a boil. Add the lemon juice and stir carefully for about five minutes, trying not to break up the pieces.

Step 3: Bottle the Jam

After five minutes boiling, take the pan off the heat and let sit for another five minutes. Spoon or funnel the jam into clean, sterilised jars and screw the lids on tightly. Leave the jam on a heat-proof surface to cool — you’ll know the jars are sealed when you hear the metal lids pop. If you’re using Tattler lids, you won’t hear a pop. This recipe does not require any further processing.

When cooled, store in a cool cupboard but refrigerate after opening. This jam has a shelf-life of 12 months.

Tattler Lids

If you’ve not heard of these before, let me introduce you. Tattler lids are reusable, dishwasher friendly, BPA-free canning lids. They’re an alternative to metal lids that are single-use and can potentially spoil food due to acid corrosion.

These lids are good for YEARS meaning that you only have to re-purchase the inexpensive rubber rings. They also fit the mouths of ordinary Mason and Kilner Jars which is pretty handy. If you’re thinking about trying them out, head over here for more information and to purchase. They’re also available in the United Kingdom.

    Looks great. You should try Marionberry or Tayberry jam.

    Not familiar with this sugar. Can you tell me how much regular sugar and maybe a box of pectin this recipe would call for.
