My mustard wasabino was starting to go to seed so it, along with a few large mushrooms were dehydrated:
They are 'being conditioned' on my work top. That is, inspected, shaken every day for a few days checking for moisture or clumping. If none found, they will go in my store cupboard.
The mushrooms will eventually get turned into powder for flavouring gravy and other things. The mustard will be added to everything as an additional seasoning.
After nearly a week of conditioning, they are fine and are not put away into my cupboard.
