I am in the process of creating a food mod and I'm wondering if it's possible to change the icon of the vanilla Food tab as well as remove certain vanilla items from that tab. I have changed it's name to "Food - Misc" in my mod's en_us.lang so that isn't a problem.

using reflection

I'm not exactly sure how to use reflection. I've tried looking it up but I haven't been able to find anything about the newer ObfuscationReflectionHelper in 1.16. I currently have this:

Field field = ObfuscationReflectionHelper.findField(ItemGroup.class, "iconItemStack");
field.set(ItemGroup.TAB_FOOD, new ItemStack(Items.COOKIE));

I have also tried replacing "iconItemStack" with "field_151245_t" but I'm still not sure how to do this.

EDIT: I'm getting the error:

IllegalAccessException – if this Field object is enforcing Java language access control and the underlying field is either inaccessible or final

Added the error at the bottom.

I get when I try to run it:

error: unreported exception IllegalAccessException; must be caught or declared to be thrown
        field.set(ItemGroup.TAB_FOOD, Items.COOKIE);

In the IDE I have:

Unhandled exception: java.lang.IllegalAccessException

That's everything.
