Editing recipe output

[Stedera]

How can I create a mod, which would for example double output of firewood recipe?
I stopped trying at
{
    "file": "game:recipes/grid/firewood.json",
    "op": "replace",
    "path": "/output/quantity",
    "value": 8
  }
which obviously does not work. Any help is much appreciated!

Try:

[
  {
    "op": "replace",
    "path": "/0/output/quantity",
    "value": 8,
    "file": "game:recipes/grid/firewood.json",
    "side": "Server"
  }
]

Unless you've got a syntax or formatting error or your folders are wrong, what you have should work; provided that isn't the entire file, you need the brackets.

Thanks for the suggestion, about folders, mine are assets/patches/game/recipes/grid/firewood.json

Oh, the game doesn't seem to like subfolders in patches.

Okay, I got it, my folders were wrong, thank you!
