I'm trying to create a shapeless recipe with a Strong poison lingering potion as an ingredient. How do I do this? My recipe currently looks like this:

{
  "group": "narutomod",
  "type": "minecraft:crafting_shapeless",
  "ingredients": [
    {
      "item": "narutomod:smoke_bomb"
    },
    {
      "item": "minecraft:lingering_potion"
    }
  ],
  "result": {
    "item": "narutomod:poisonbomb",
    "count": 1
  }
}

Please help!

Use a partial nbt ingredient. Then just specify the tag like any other potion tag.

oops forgot to mention its for 1.12.2. can i still use nbt in the json?
