Motivations by the company have been explained far better than I could by the other replies, but from both mine and other people’s experience, some software when installed via snaps seems to perform badly compared to any other method of installation (notably chrome and firefox i think). Also snap isn’t really bringing anything special to the table whereas flatpak has a more interesting containerised approach from what I’m aware.
In any case with the way ubuntu’s going I’m really not over the moon with anything canonical (and i don’t think I’m alone)
My thoughts for something like that would be either mustard (dijon, although it has a similar sort of pungency to horseradish), peppercorn sauce or red wine and rosemary butter (or similar)? Whipped chive butter sounds quite nice!
Unless I’m drastically misinterpreting what you’re trying to make - I assume you’re referring to some kind of sauce or flavouring for medallion steaks?
