I have seen this recipe by James Martin before - but thought I would try it for ZWT3! I had all the ingredients to hand - and the mustard was superb - we ate it with some home-made beef & potato pies, excellent choice of condiment. It took my mustard nearly an hour and a half to thicken - and then it was not as thick as commercial mustards, which is good! I think this will be much more refined after a few weeks left to mature - an excellent condiment for red meats however.Thanks for posting! FT:-)

French Tart June 04, 2007

I made 4x this recipe to give out as Christmas gifts and it made 12 very small almost baby size jars. At first the smell of vinegar was overwhelming so I got a little scared and added probably 1/2 cup of good honey to it. I don't think I needed to do that but it turned out fantastic. I waited 4 days before trying some on bread and wow! It starts off a little sweet and then pops SPICY in your mouth. I ended up calling it Spicy Guinness Mustard as it had quite the kick but so far one person I gave it to for Christmas has tried it and said they loved it too. Great Recipe!!
