I love mustard and buy everyone that looks intriguing. For hot dogs I prefer mustards other than bright yellow salad mustard. I generally use Nathan's brand mustard but I've had mustard @ hot dog stands that I've liked better. I recently bought some Inglehoffer Stone Ground Mustard. It's a good mustard but has a touch of sweetness that I don't like on a hot dog. It's great to make salad dressing though. I also don't like Dijon mustard, grainy or plain, on hot dogs. Any suggestions for hot dog mustard that I can buy in supermarkets (I have Shoprite, Trader Joes & Whole Foods nearby) or online? Thanks!
