ComputerCraft: 1.80pr1

The fact that similar errors are occurring for minecraft:recipes/food/pumpkin_pie, minecraft:recipes/food/mushroom_stew and several others makes me pretty sure this isn't a ComputerCraft bug - especially as I'm not getting such errors with ComputerCraft on its own.

I'd presume there's another mod messing around with recipe loading somewhere. Maybe try removing some mods and seeing if the error still occurs.
