hey there i tryed to remove IE recipes by types like:
event.remove({type: 'immersiveengineeringAlloy'})
event.remove({type: 'immersiveengineeringBlastFurnace'})
event.remove({type: 'immersiveengineeringCrusher'})
event.remove({type: 'immersiveengineeringArcFurnace'})
event.remove({type: 'immersiveengineeringMetalPress'})
event.remove({type: 'immersiveengineeringSawmill'})
but the recipes are still loaded

You'll have to use the actual name of the type, like immersiveengineering:alloy or immersiveengineering:blast_furnace_fuel
