350 grams of castor sugar
Zest and juice of 1/2 lemon
Boil the jam jar for 10 minutes. Remove from heat and let cool.
Turn the heat up to medium-high and boil the mixture rapidly for 10-15 minutes, stirring occasionally. Add the spices (powder the cloves)
Place a tsp of jam in the fridge and after 20 minutes wrinkle the surface using your fingers .If the jam doesn't wrinkle the first time but sticks to your finger like a thick liquid rather than jam, keep boiling it for another 5 to 10 minutes and then test again. If jam is ready then remove the saucepan from heat and let it sit for 10 minutes or until the edges of the jam sets slightly. Pour jam into a warm jam jar till the brim (warming will ensure moisture is not present) and then let it cool completely before sealing.
