I love mustard.
French's Yellow Mustard if we're going to be exact.
When my husband and I married someone gave us a Costco gift card. I asked if it didn't make sense to buy a gallon of mustard as part of our shopping that day. He looked at me as if I were absurd. So we skipped it. Six months later my mother was visiting and I heard him explain what he thought at that time. There was no way we were going to eat a gallon of mustard. After 6 months he now understood that I probably could consume that much all by myself. That said there are other mustards that I have enjoyed from time to time, but I always return to standard ol' yellow. As a side note my son likes mustard and does not like ketchup.
So imagine my delight in my meandering days of yore when I discovered the delightful Mount Horeb Mustard Museum. They also produce an e-newsletter that's kind of fun. So if you're looking for some entertainment check out http://www.mustardmuseum.com/. The site is mainly a sales page for more types of mustard than you can imagine along with news about the museum.
