Recipes

Since Palladium Addon Packs function as datapacks, you can use any normal vanilla recipe json file in an addon.
An online tool to generate files for that is https://crafting.thedestruc7i0n.ca (make sure to select the correct game version).

Tailoring

Palladium also adds 2 new custom recipe types, for its Tailoring Bench. Both allow you to define recipes for it.

palladium:item_tailoring

Field	Type	Required?	Default/Fallback	Description
results	object	required (must contain at least one item)	—	Map of armor slots to the result items. Possible slots are: head, chest, legs, feet.
ingredients	array	required (non‑empty)	—	Shapeless input ingredients. Each element is a SizedIngredient object (see table below). If empty, deserialization fails.
tool	Ingredient	required (must be non‑empty)	—	A standard Minecraft Ingredient JSON describing the required tailoring tool. If empty/invalid, deserialization fails.
title	Text Component	required	—	Localized text shown for the recipe title. Uses Minecraft Component JSON format (can be a raw string or structured object).
tool_icon	Resource Location	optional	null	Resource location for the icon used in the tailoring menu tool slot. Example: "minecraft:item/diamond_sword" or a custom texture location.
category	Resource Location	optional	null	Resource location identifying a category for grouping recipes together in the tailoring menu recipe book.
requires_unlocking	boolean	optional	true	If true, the recipe requires unlocking before it appears and can be crafted.

ingredients

Each element must be a non‑empty Ingredient with a positive count.

Field	Type	Required?	Default/Fallback	Notes
ingredient	Ingredient	required (non‑empty)	—	Standard Minecraft Ingredient JSON (item, tag, or alternatives). Cannot be empty here.
count	integer (>= 1)	optional	1	Number of items required for this ingredient. Must be positive.

Example

{
  "type": "palladium:item_tailoring",
  "results": {
    "head": "minecraft:diamond_helmet",
    "chest": "minecraft:diamond_chestplate",
    "legs": "minecraft:diamond_leggings",
    "feet": "minecraft:diamond_boots"

    {
      "ingredient": {
        "item": "minecraft:diamond"
      },
      "count": 24
    }
  ],

  },
  "tool_icon": "palladium:item/empty_tool_slot_shears",
  "title": "Diamond Armor",
  "category": "test:vanilla_armor",
  "requires_unlocking": false
}

palladium:suit_set_tailoring

Works essentially the same, but can directly use a suit set to declare its results.

Field	Type	Required?	Default/Fallback	Description
suit_set	object	required	—	ID of a suit set that will be the result of this recipe
ingredients	array	required (non‑empty)	—	Shapeless input ingredients. Each element is a SizedIngredient object (see table below). If empty, deserialization fails.
tool	Ingredient	required (must be non‑empty)	—	A standard Minecraft Ingredient JSON describing the required tailoring tool. If empty/invalid, deserialization fails.
title	Text Component	required	—	Localized text shown for the recipe title. Uses Minecraft Component JSON format (can be a raw string or structured object).
tool_icon	Resource Location	optional	null	Resource location for the icon used in the tailoring menu tool slot. Example: "minecraft:item/diamond_sword" or a custom texture location.
category	Resource Location	optional	null	Resource location identifying a category for grouping recipes together in the tailoring menu recipe book.
requires_unlocking	boolean	optional	true	If true, the recipe requires unlocking before it appears and can be crafted.
