GTCE stores all recipes in a RecipeMap. To get them, you need import mods.gregtech.recipe.RecipeMap to your code.

Recipes are categorized into their machines, call RecipeMap.getByName(machineName) to get specific recipes and builder.

List of available machines

Not yet implemented:

Primitive Blast Furnace uses different syntax from normal recipes. For example:

import mods.gregtech.recipe.PBFRecipeBuilder;

//Primitive Blast Furnace
    .input(<ore:ingotCompressedWroughtIron> * 1)
    .output(<ore:ingotSteel>.firstItem * 1)

//Remove recipes from PBF
import mods.gregtech.recipe.RecipeMaps;

for recipe in RecipeMaps.getPrimitiveBlastFurnaceRecipes() {

Builder information

After getting a instance of RecipeMap, you can define recipes by using their builder.

Builder method calling:


It is a bit like Stream<T> in Java, with fully functionally to control your recipe’s behaviour.

Example for EBF:

// Electric Blast Furnace
val blast_furnace = mods.gregtech.recipe.RecipeMap.getByName("blast_furnace");
    .inputs(<ore:ingotCompressedWroughtIron> * 1)
    .fluidInputs([<liquid:oxygen> * 500])
    .outputs(<ore:ingotSteel>.firstItem * 1)
    .property("temperature", 1000) //this is a minimal temperature at which the item will be smelted

Some of properties assignable to .property() method:

Name Description
explosives Implosion Compressor, amount of explosives
circuit Integrated Circuit-configurable machines. Configuration of circuit
temperature Blast Furnace. Minimum temperature requirement.


Name Description
amplifier UU Amplifier. Amount of UU Amplifier outputted.
eu_to_start Fusion Reactor, EU to start fusion

You use it just like the “temperature”:

.property("circuit", X)//, where X is the integrated circuit configuration
.property("explosives", Y)//, where Y is the amount of explosives required to make a recipe work

More useful methods:

.chancedOutput(<itemstack>, 0-10000) (10000 is 100%)
.duration() // in ticks
.notConsumable(X) // where X is a CT id. Works as .inputs, but the item doesn't get consumed
.hidden() // if the recipe is hidden from the JEI
.chancedOutput(<itemstack>, 0-10000) (10000 is 100%) // not valid for every machine. some of them use that method. The most notable one is macerator
.EUt() // EU per tick


Removing a recipe is done by recipe instance itself, so you have to find a recipe first.


val compressor as RecipeMap = RecipeMap.getByName("compressor");

// findRecipe(long voltage, IItemHandlerModifiable inputs, IMultipleTankHandler/List<FluidStack> fluidInputs)
compressor.findRecipe(2, [<minecraft:redstone>], null).remove();
