After many healthy jam recipes, we felt our collection wasn't complete without a glorious cherry preserve. So, today we want to show you how to make a delicious sugar-free cherry jam with just two simple ingredients. It's ready in only 30 minutes, pan to jar!
Classic jam is made with fruit pieces and white sugar, used in a 1:1 ratio. They're stewed in water until they form a jelly-like mixture thanks to the action of pectin. Pectin, a soluble fibre, creates a mesh that traps in the liquids, forming a gel. Because some fruits, including cherries, are low in natural pectin, pectin powder is often added to the mixture to help the jam set.
To make our recipe without refined sugar or pectin, we relied on only two wholesome ingredients: sweet cherries and ground flaxseeds. Sweet cherries are naturally rich in sugar, while flaxseeds pack lots of soluble fibres, thus replacing the action of pectin. All you have to do is simmer them with water, then blend them, and you'll have a glossy cherry jam, full of flavour and goodness.
Tart cherries like the Montmorency and Morello varieties are a staple for cooking, baking, or making jams; sweet cherries, instead, are mainly used for eating fresh. However, to keep this jam recipe sugar-free, we needed our cherries to taste sweeter, and therefore, we opted for sweet cherries. Still, if the jam feels a bit sour to you, we'll give you the option to add a sweetener in the tips below.
As for the flaxseeds, make sure you're using the ground ones, not whole flaxseeds, or they won't work. You can find them at your local supermarket or buy them online. You can also replace them with chia seed in equal amount, and you'll get the same results.
Compared to a store-bought preserve, our homemade cherry jam has half the calories and 60% fewer sugars. Because it contains only naturally occurring sugars, it's safe for those with diabetes or on a low carb diet. You can spread it on toasted bread, stir it into yogurt, or spoon it in your morning oatmeal. It's also perfect for preparing desserts, filing pies and pastries.
