I bought a jar of this years ago and carted it all the way back to the US. Boy is it good. I make my own mayo using the now-popular stick blender method and this is just awesome as the mustard in your mayo. If I could eat bread it would make a great sandwich (gee I miss those carefree, bread-eating days....ah youth). It is also dynamite in a vinaigrette. Don't be surprised that it doesn't look enormous. But it does have a full 16 oz inside. And don't drop it on your foot. It's a very heavy ceramic crock.
