I've been meaning to make my own mustard condiment for years, but never got around to it for one reason or another. If I had realised how easy it is to get a really tasty result, I would have done it years ago, instead of prevaricating. The only (mildly) difficult part is sourcing the mustard seed. You can buy one of three mustard seed types: white/yellow, brown and black. The three seed types are increasingly hot in that order. If you live in a city you probably have access to a wholefoods supplier, and for everyone else you can probably get mustard seeds fairly cheaply via the Internet. Now that we have the difficult part out of the way, we can proceed to the easy part: making the mustard condiment (sometimes called prepared mustard).
