prepared Dijon-style mustard

Normally, in EN, when I read 'prepared', I would understand 'bought from the shop ready-made' — unless it specifically stated "that you prepared earlier"

Thank you a lot for the explanation. In Poland we have "horseradish" as a root and in a jar but if you say 1 spoonful of horseradish, I think it is clear.

...here means 'made up' — in England, mustard is available as a dry powder, as well as ready mixed with water, vinegar, etc. in jars. Hence why the recipe specifies which of the two type to use.

Generally speaking, here in France, this sort of mustard is only available 'ready-made' hence there is usually no need to specify; I don't know what the case is in Poland.

In the UK, horseradish is less commonly found other than in made-up form, but perhaps the writer just thought it was best to be on the safe side! And oddly enough, fresh horseradish is actually probably more like to be available here in France.
