You always make such inspiring and beautiful dishes. This is another I need to try! I don't have mustard, but I wonder if I can use any other flower from the mustard (cabbage) family? The ones I have seen all look the same: broccoli, kohlrabi, and actual cabbage have yellow flowers like that. Right now I am growing kale.
That might work but I think none of these are actually as savory as the flowers of true mustard greens.
