i have recipe problem with tag

I made a tag "salty"

and use that tag for recipe

but recipe was not worked

tag json file was

{
  "replace": false,
  "values": [
    "chironcraftkorean:salt",
    "chironcraftkorean:rhuschinensisfruit"
  ]
}

and recipe file was

{
  "group": "chironcraftkorean",
  "type": "minecraft:crafting_shapeless",
  "ingredients": [
    {
      "item": "chironcraftkorean:napacabbage"
    },
    {
      "tag": "salty"
    }
  ],
  "result": {
    "item": "chironcraftkorean:baechujjanji",
    "count": 1
  }
}

how can solve that?
