Spiced Plum Jam (and a Digital Jam Scale Review)

Recipe for spiced plum jam, perfect on brioche, croissants and with cheese – plus a review of the new Neo Cook Jam-making Scale by Terraillon.

Terraillon Digital Jam-Making Scales

Just as I finished making a batch of French Apricot and Lavender Jam, I received these rather clever jam-making scales.

They came from the French digital kitchen scale experts at Terraillon.  As you know, I believe that digital scales are a real kitchen necessity if you’re aiming at CONSISTENTLY SUCCESSFUL RESULTS  – especially in baking. For more, see my article why you need to weigh your ingredients for successful baking.

However, when I heard about these jam-making scales, I had no idea what they were. So they came just in time to make this spicy plum jam and test them out.

What makes them different to classic digital kitchen scales?

The Neo Cook Jam scales have a clever jam button. Here’s how:

• Switch the scales on, place on your container and set the scales to “0”.
• Weigh your prepared fruit (here it was 1.551kg), hit the jam button, and it tells you HOW MUCH SUGAR IS NEEDED for the weight of fruit.
• Continue to add the indicated amount of sugar (here it was 1.008kg); as you add, the amount decreases until the perfect weight is achieved, finishing at zero.  It’s so easy!

Ratio of Sugar to Fruit in Jam-Making

The scales are set by default as 750g sugar to 1 kilo of fruit but this ratio can easily be changed by hitting the jam button for 3 seconds and selecting your desired amount of sugar quantity per kilo.
I easily RESET the ratio of sugar to 650g per kilo of fruit and as you can see, discovered that I had over 1.5kg of plums and so needed just over a kilo sugar.

Metric vs Imperial Measurements

No problem if you don’t like working in grams, kilos or millilitres: simply set the scales to imperial ounces, lbs and fluid ounces at the switch of the unit button.

Things I particularly like About the Terraillon Jam Scales

I recommend these innovative scales even if you don’t use the jam feature. I also love the additional timer and hold buttons so much that I’ll be using them for other baking and cooking. (I see they’re available in the UK at Lakeland, who have EU delivery.) Here are reasons why I love them for jam-making:

• The Jam button is clever. This is perfect for weighing irregular quantities of fruit rather than sticking to a kilo etc. The result is no waste;
• Its Timer Function is useful: I often discover mid-flow that I’ve finished a packet of sugar and need to find another one in the cupboards. In this scenario my previous scales would normally switch off so this is a great feature. You can set the timer for a couple of minutes or even up to 99 minutes;
• There’s also a pause button: useful for heavy containers or packages that may prevent visibility of the screen;
• My previous digital scales use 4 AAA batteries: the Terraillon Neo Cook Jam Scale uses only two;
• The scales are light-weight, slim so easy to store. They’re stylish, with an easy-to-clean glass top so remain pristine;
• Jam-making is made quick and easy: jams will be consistently perfect using these scales, no matter how much fruit you have each time;
• Update summer 2022: I am still using the scales and find that making jam with them makes the whole process even easier. Since I have had them, in 6 years I have only changed the batteries once and they work like crazy.

What Kind of Plums are Best for Jam?

Any of the European plums (Prunus domestica) are ideal for making jam. For this jam with added spices, I prefer the darker purple varieties such as Ente plums (known as Prune plum as used to make prunes), damson or the red-yellow Victoria plums. Outside of France, the Japanese or Chinese plum will also work deliciously well.

If you love greengages (Reine-Claude) or mirabelle plums, then replace the spices with vanilla.

For much more, see the French market page on plums.

Do I Need Pectin to Make Plum Jam?

Plums are naturally high in pectin there is no need to add any extra pectin.  So, I use normal granulated sugar without the added pectin in special jam sugar. I also add a touch of lemon juice, which is also high in pectin and acidity. These two factors help the jam to thicken naturally without any help.

There’s also no need to peel plums to make this jam – just take out the stones and that’s it!

What Does Spiced Plum Jam Taste Like?

As plums are both sweet and acidic, the added sugar makes a well balanced jam that’s not too sweet. As sugar is kept to a minimum, the tartness of the plums shines through.  The added spices (cinnamon, ginger, cloves and aniseed from the pain d’épices) make the taste quite warm and even slightly Christmassy.

As a result, spiced plum jam is great given as holiday gifts. It accompanies strong French cheeses well and foie gras for holiday menus – so don’t forget to add this to your festive cheeseboard. If you love jam with cheese or foie gras without the spice, then try this Corsican Fig Jam.
