This is an old South African recipe for curried beans, a bit like picallili. I've never made them but the recipe comes from my Mum's recipe book and she had a reputation for making very good things.
Boil 4 lbs green beans (she used to use French but I'm sure you could use any) with 2 lbs of sliced onions in 4 cups of water (thats 1l or just under 2 pints) until the beans are just cooked. You then add 3 1/2 cups brown vinegar (875ml SA recipes often use cups ), 2 cups sugar (500g), 2 dessertspoons of salt (about 20g) 2 dessertspoons curry powder (again about 2og) 2 tablespoons cornflour and a few cloves.
Boil the whole lot for five more minutes and bottle.
I'm not sure how much this makes but I should think lots

so you may want to scale it down.
