Because we’re almost to St. Patrick’s Day, I thought it was a good idea to show you guys how to make Guinness mustard. I’m serious about his homemade mustard! So here we go!
I never in a million years thought I would be making my own whole grain mustard, let alone this Guinness recipe because most well-stocked grocery stores offer a large selection of gourmet mustard. I also thought that the process required special equipment. A few months ago, while reading a food magazine inspiration struck.
Homemade mustard is like a science experiment.
Although the process is fairly simple, there is some serious chemistry going on here. The chemicals inside the mustard seeds react with the cold liquid (Guinness). Something to keep in mind: A colder liquid produces a stronger mustard, while a lukewarm liquid will render a more mellow flavor.
Mustard is one of Europe’s few native spices
It was widely used by its ancient civilizations. For example, the Greeks and Egyptians used it to spice their dishes. The Romans also loved their mustard; their Latin name for it is mustrum ardens which means” burning must”. They were also probably the first to experiment with making mustard by adding un-fermented grape juice (verjus) to mustard seeds.
The Romans also imported mustard to Spain and Gaul. Consequently, in medieval France, spice sellers who sold mustard sold it under the classification of “epices d’enfer“, or spices from Hell. Although mustard is often associated with Europe, the Chinese have cultivated mustard for about 2500 years.
And, now that I know how to make Guinness mustard, next I can experiment with other liquids, champagne, maybe?
By the way, you should let this mustard mellow for two or three days before eating.
