Against my will, jars of jam. My husband insists on regularly buying it, despite the fact that no-one in our family eats it, and storing it IN THE FRIDGE, despite the fact that IT IS A PRESERVE, and space in the fridge is AT A PREMIUM. I then take the fridge-jam, and put it on a shelf, where he can’t find it, and so has to buy more - thus continuing this cycle of abuse. The blackcurrant jam is the worst. NO ONE, IN THE HISTORY OF EVER, HAS ASKED FOR, OR WANTED, BLACKCURRANT JAM. IT’S JUST A PURPLE SEED-MULCH. And yet, I’ve “collected” three jars. Jam is my enemy.
