I learned that Battered Fish can't be Quick Synth'd the hard way after I gathered all my mats and received the Big Red Text of Nope when I went to craft them... and that is the story of how I made no less than 261 servings of Battered Fish manually (it was for the alt characters for myself and some friends).
That being said, they're very easy to craft and making a full set needed to get all the vouchers to exchange for everything is still arguably faster than doing the jump puzzle, so it kind of balances out? Maybe?
