My late grandmother has made this vinegar based coleslaw for as long as I can remember. No idea where she got it, or if she made it herself, but I love it, especially over a BBQ pulled pork sandwich.
Help yourself bro's...
Straight from the decades old, faded note card in my grandmothers writing...
Slice or shred one head of cabbage, green bell pepper, onion or scallions, and a small jar of pimentos - drained. (for clarification I use 1 large green bell pepper, and however much onion you like. I've made it without either one, and it's been good still as well)
In a small saucepan: Mix 3/4 cup vinegar, 1/2 cup sugar, 1/2 tsp dry mustard (the powdered yellow mustard stuff), 1 1/2 tsp salt, 1 tsp celery seed and 1/2 tsp mustard seed.
Bring to a boil, remove from heat, and allow it to cool down to room temp. (I do the sauce first for this reason so it's cooling while I do other stuff) After cooled, add 1/2 cup salad oil (veg oil, olive oil, don't matter), stir, and then pour over cabbage mixture.
Cover tightly and refrigerate!
You can eat it right away, however it's much better after chilling, and letting the sauce break down the cabbage mixture a bit. I usually make this at night, and then let it chill over night, and it's so amazing the next day.
