This is my simple, delicious and 3 ingredient how to make rhubarb jam (without pectin) at home recipe. Are you ready to make your own rhubarb jam at home?
Heads up, before we start. Make sure you sterilise all your equipment. Jars, lids, tongs, spatula, funnel. All of it. Read this post on how to sterilise jars in the oven.
Jam making and safety
To effectively and safely store food at room temperature you need a preserver. In this case, we're using lemon and sugar. If you change the ratios of this recipe, there's no guarantee it will be safe to store on the shelf. The same goes for jar that don't have an appropriate heat seal. This is why we check. Always follow a recipe with correct preserving ratios AND always work with the cleanest equipment possible (sterilised).
