What We Bring
Three mustards from St. Charles
Original Sweet & Spicy is Adora Spencer's recipe from 1935, the one that started it all. It's named for Grandpa, but she really gets the credit.
Hot & Spicy has about the heat of a jalapeño or cayenne pepper. It's great on brats and burgers.
Horseradish is our best seller. It's mild to medium, so it won't wipe out your sinuses.
All three are gluten free.
Can't make it? All three are in our online store, and the retailers page lists the shops that carry them.
