So turn that burner down, and let your mixture cool off a bit before adding sugar! You don't want to dump a bunch of sugar into a boiling pot.

How do you prevent crystals in grape jelly?
Strain through a damp jelly bag or double layers of cheesecloth. During storage of grape juice, white crystals often form in the bottom of the jar. They are tartrate crystals and are harmless.

What causes crystallization?
Crystallization is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. If a saturated hot solution is allowed to cool, the solute is no longer soluble in the solvent and forms crystals of pure compound.
What kind of ingredients can interfere with crystallization?
FATS: Fatty ingredients such as butter help interfere with crystallization — again, by getting in the way of the sucrose molecules that are trying to lock together into crystals. Toffee owes its smooth texture and easy breakability to an absence of sugar crystals, thanks to a large amount of butter in the mix.
What factors affect crystallization?
Both the rate of formation of nuclei and the rate of crystallization are affected by the nature of the crystallizing substance, the concentration, the temperature, agitation, and the impurities present in the solution.

Full question
My Chilli Jam was nicely set and smooth when I made it first and served at Christmas, but after a few months it crystallised. Can I prevent this or correct it?
Our answer
Nigella's Chilli Jam (from NIGELLA CHRISTMAS) should keep for up to a year, if stored in a cool, dry place away from direct light. Opened jars should be kept in the fridge and used within one month. If the crystals are forming on the top of an opened jar then it is probably caused by the jar not being sealed tightly and some evaporation ocurring.
