Does anyone have a good recipe for homemade mustard?

My son (11) loves to cook. He usually cooks lobster, shrimp concoctions, and meat and potato dishes. He noticed that there are not many ingredients in a jar of conventional store-bought mustard and decided he would like to try making some himself. Please post the recipe , including all the ingredients, quantities, and mixing/heating tricks that you might use. Also, please suggest dishes that this mustard tastes best with. Thanks so much. I'm looking forward to seeing how this turns out and to sampling the final product!Does anyone have a good recipe for homemade mustard?
I have never made mustard before, mainly because it is so easy to just go buy it at the grocery store. Maybe you can try these suggestions...
