What? Brits make their own... mustard
Of course.
they buy the seeds and grind them? Do they grow their own plants to harvest the seeds?
That would be too much hassle. We just buy the powder. You can get ready made as well however it loses its kick very quickly.
It's handy as a cooking ingredient too. When imports moved to PL, I looked and actually bought some seeds to grind however it was a drag to do and the seeds were obviously of a mild variety. You can sometimes get tins of powered in Kuchnie Świata at a crazy price so I just bring it with me now.
