This is an example of how to use .forEachRecipe() for changing or adding new recipes using existing ones.

ServerEvents.recipes(e => {
  // 2x slabs -> 1x plank through shaped crafting
  e.forEachRecipe({ type: 'minecraft:crafting_shaped', output: '#minecraft:slabs' }, r => {
    let ingredients = r.originalRecipeIngredients // returns a List<Ingredient>
    let output = r.originalRecipeResult           // returns an ItemStack
    e.shaped(ingredients[0], ['S', 'S'], { S: output })
  })

  // 1x stair -> 1x plank through stonecutting
  e.forEachRecipe({ type: 'minecraft:stonecutting', output: '#minecraft:stairs' }, r => {
    let ingredients = r.originalRecipeIngredients
    let output = r.originalRecipeResult
    e.stonecutting(ingredients[0], output)
  })

  // change the output from logs to planks from 4x to 2x (this will replace old recipe)
  e.forEachRecipe({ type: 'minecraft:crafting_shapeless', input: '#minecraft:logs', output: '#minecraft:planks' }, r => {
    let ingredients = r.originalRecipeIngredients
    let output = r.originalRecipeResult
    e.shapeless(Item.of(output.id, 2), ingredients[0]).id(r.getOrCreateId())
  })
})

You can get the recipes json with r.json and then extract the time from that

This would Check for the Item that willve smelted

I don't think smelting recipes takes "coal" per se, it is any burnable items that goes to other slot unrelated to recipe

you need to translate duration to "coal"
