I think the ingredient requirements need to be reduced all around. Compare to Wrath Fish Feasts, which I think were about right: 2 each of 3 kinds of fish, plus 1 Northern Spices. You could farm up a stack or two before raid easily. Farming for your raid food shouldn’t take longer than your raid.
ETA: While farming for just the Viper Fish, have farmed enough Mauve Stingers for literally 375 Fragrant Kakavia (198 Stamina)
The incredible tedium of trying to farm up 300 each of Viper Fish, Stringy Loins and Meaty Haunches for a stack of 20 feasts is terrible, then add the crates on top of that? Ugh. The only thing that can be farmed in a reasonable time is the Minnows.
