Crush and grind the seeds or use mustard powder. Add enough boiled water to make a paste on the bottom of a bowl. Cover with cold water and slowly knead the mustard paste without dissolving it into the water. Let stand and drain off the water. Repeat several times. This removes the aggressive acids known to take the skin off your chest caused by a mustard plaster. Let stand to evaporate most of the water and then combine with your favorite vinegar, and spices, and some honey.
We've been buying mustard from them for years. (They have about 500 different mustards at any one given time.) Under "mustard making supplies" they have several different mustard seeds and flours. http://mustardmuseum.com/
