Steps to Reproduce the Bug

1. Add JEI and CraftTweaker to your modpack.
2. Remove the Tipped Arrow recipe with CraftTweaker, for example: recipes.removeAll(); or recipes.remove(<minecraft:tipped_arrow>); or recipes.removeByInput(<minecraft:arrow>);.
3. Launch the game.
4. Click on any Tipped Arrow: JEI still shows the recipe (seen below), even though their crafting recipes don't work (also see below).

Expected Behavior

JEI shouldn't show the recipe, since it does not exist anymore.

JEI doesn't actually check if the recipe exists:

Actual Behavior

JEI still shows the recipe:

Even though the recipe doesn't work:

This should be easily fixable by just adding an if clause:
if (recipeExists) {addRecipe();} instead of just addRecipe();

The issue still persists, so it should remain open.

Thanks for the report!
This issue has been fixed in later versions of JEI but the fix hasn't been backported yet. I can fix this for 1.12 soon

This should be fixed in jei_1.12.2 version 4.16.1.1004
