I also get mine from Mala, and now that I'm a Patreon supporter of Chinese Cooking Demystified I get a little discount as well. Last order I got the regular but also the flowers. I haven't delved into the difference yet, but love them both. I'm using them on all sorts of random foods, including a vinegar ice cream, with the same process - lightly toast, grind, add, finish with some vinegar or acid element. I'm a bit addicted.
ETA: As if my computer were reading my posts, Mala market sent a marketing email just as I hit POST, with a new shipment of different chiles and peppercorns.
