External compat mods cannot add conditionals to Create: Liquid Fuel JSON as they do not fit under the category of recipes, and do not properly respect conditionals manually.

I made Engineered Compatibility and was looking to add compat with both Create: Liquid Fuel and Liquid Burner, to allow for either to be used in packs.

However, as the fluids I am seeking to add do not necessarily exist - namely, IP fuels - I get a datapack loading crash if I try to implement conditionals. Attached below is a recipe-less Forge/NeoForge conditional JSON to show the syntax.

{
  "type": "forge:conditional",
  "recipes": [
    {
      "conditions": [
        {
          "type": "forge:mod_loaded",
          "modid": "createliquidfuel"
        },
        {
          "type": "forge:mod_loaded",
          "modid": "immersivepetroleum"
        }
      ],
      "recipe": {RECIPE GOES HERE}
    }
  ]
}

Thanks for the suggestion, although since it's a mod, I do have a temporary solution if you are willing to give up the time, I respect your choice if you don't. What you can do is dynamically load a class to add the recipe manually to one of the classes that have the list of blaze burner fuels.

Ah, it's not a mod yet. Thank you for the suggestion, and I may implement it if by the time I get around to turning Engineered Compatibility from a datapack-mod into a proper mod it's not implemented!
