She wants to make chow chow, which is a "Sweet and sour" mixture of pickled veggies. In the Dutch country we usually use cider vinegar, apple cider, some sugar, cinnamon and cloves and all sorts of cooked and raw veggies.
fava beans and limas
sugar snap peas
Celery strips, Melon rinds
cucumebr slices and juliennes
Weve never added green tomatoes
also we add whole pepper corns (Telicherry holds up really well) and some folks add hungarian wax peppers and one jalepeno per jar
These are best made as a refrigerator pickle mix. If its done up as a canned treat, all the veggies are put in the sweet brine raw and then brought up to a canning temp and lidded up.
Chow chow is a great side dish for meat loaf or ham steaks
