I recently tasted some whole grain mustard coleslaw at a bar/restaurant called Waterfront ale house in Brooklyn, NY and thought it was the best tasting coleslaw I've ever tasted. It was sweet, tangy, light with good crunchness. It wasn't heavy like the ones with mayo only based.
nyone has a good whole mustard coleslaw?
finely shredded green cabbage
finely chopped red onion
white wine vinegar
sugar (just a little)
salt and pepper to taste
I typically mix the dressing ingredients and do the taste test before applying it to the slaw. Ingredient amounts vary, depending on individual taste. But this will get you started on creating something you like.
