recipes not working for my mod.

[TheCragies]

I very recently started getting into Minecraft modding, and I cant seem to get my recipes working. I have created a hamburger item, textures and everything works except the crafting part.
I created the .json file at: assets/biasmod/recipes/hamburger. I tried switching the items in the recipe between minecraft's own items to my own modded items, but nothing. I  also tried inserting 
"item": "biasmod:item/hamburger". I have tried downloading other peoples recipes as well and just tried if they worked but nothing. From my understanding these recipes should't have to be loaded or registered but for some reason mine is not being loaded.
Here is the .json file
 

{
  "type": "minecraft:crafting_shaped",
  "pattern": [
    "AAA",
    "ASA",
    "AAA"
  ],
  "key": {
    "S": {
      "item": "biasmod:example_item"
    },
    "A":
    {
      "item": "minecraft:stone",
      "data": 0
    }
  },
  "result": {
    "item": "biasmod:example_ore",
    "data": 0
  }
}

here is a other .json file I have also tried
 

{
  "type": "minecraft:crafting_shaped",
  "pattern": [
    " # ",
    " # ",
    " # "
  ],
  "key": {
    "#": {
      "item": "minecraft:red_mushroom",
      "data": 0
    }
  },
  "result": {
    "item": "minecraft:emerald_block",
    "count": 1
  }
}
