First wash and scald some(4 of the 500 ml)preserve bottles then set them in the oven at 350* to sterilize. (I keep them in there a half hour at least~ it takes a half hour to prepare and cook up everything so start this right away). Set your lids in hot water to soften.
Cut up bush beans in one inch pieces(You need at least 8 cups). Wash and set to cook with 1 tsp salt until tender but not overcooked.
Meanwhile mix 1/2 cup flour, 1/2 cup dry mustard powder, 2 tsp salt and 1 tsp tumeric together. Then add 1/2 cup of your liquid from your cooked pods, whisk well to make a thick paste...no lumps.
Meanwhile bring 2 cups of white vinegar, 1 cup white sugar and 1 tsp celery
seed to a boil.
When your pods are cooked, drain well. Then take some vinegar mix and slowly add to the mustard paste(to stop the flour from cooking to fast), then pour all mustard paste into the vinegar mix and cook up for 5 minutes. Por back into the drained bean pods and boil up two minutes more.
Pour into hot jars and seal. delicious.
