- 750 grams of chopped, trimmed rhubarb
- 250 grams of washed, chopped ripe strawberries (adds colour and flavour to the jam)
- 1 kg of sugar (I think I actually used a little less than 1 kg – probably about 900 grams but if you are going to store your jam – you do need to use enough sugar to set the jam properly and thus prevent it from going bad – the standard ratio is equal quantities of fruit and sugar)
- juice of one fresh lemon
Begin by washing and sterilizing jam jars. I set these in the oven for about 10 minutes at 250 deg. F. In the meantime, bring the fruit and lemon juice to the boil in a large, heavy stainless saucepan. Cook over medium heat (hot enough to maintain a low boil) for about 10 minutes stirring frequently. Add the sugar and bring the jam back to the boil over med-high heat – taking care not to burn the jam, stirring constantly once the sugar is added. It will take about another ten minutes of cooking (20-25 minutes in total) for the jam to thicken and reach the jelly stage. For instructions on this check here.
Once the jam is sufficiently thickened, remove from the heat, stir for one minute, pour into sterilized jars, and seal immediately.
