@Playalot I did notice Wasabi (maybe) being sold at the Produce stand once and I know they're also sold at the Spice Festival.
To be honest, I haven't paid any attention to those spices after weeks of chasing around for wasabi months ago, because the food stall recipes can be prepared without them.
Thanks for the heads-up. I'll be sure to check early next week.
If nobody's covered them yet, I also want to list the Selvadora food stall recipes and cantina drinks then, too.
Edited to add (04/18/2018): Every time I stop by the produce stall, I've only found wasabi...
