Salad dressings and barbecue sauce mostly. I live in North Carolina and Eastern North Carolina BBQ sauce for pork is vinegar based. Recipes can be found on line and are close enough.

Also refrigerator pickles, a red cabbage recipe, cole slaw dressing and beet pickled eggs. These 4 generally need a sweetener of choice. I'm sure there are other things but those come to mind.

I add baking soda and clean my shower with it lol I also use it as a dressing for salads and cucumber. Sometimes I drink a cap full sometimes I don't.

I put a cup along with hot sauce and a bunch of spices to make my 10 pounds of chicken I bake each week.

Brings out the flavor.

I use it in my favorite psyllium bread recipe, or add it to bone broth ( it helps draw out nutrients from the bones) and as a starter when I make my pro-biotic, naturally fermented home made saurkraut.

I also drink it diluted in water (and tell myself it's lemonade) when I notice alot of hard tartar buildup on my teeth as my body tends to get rather alkaline from eating keto.

I use it in a few marinades as it's a good tenderizer. Diluted it's also a decent hair rinse if you don't mind the smell. I also use it or plain white vinegar to clean my shower door, mop the floor, as a surface cleaner, etc.
