A template component that can take a serialized ingredient would be fantastic, with support for the itemstacks rotating through as they do in recipes.

It is currently impossible, to my knowledge, to display multiple valid items that could be used in your custome templated recipes, without using a modded component processor and a corresponding custom template component.

This issue is stale because it has been open for a while with no activity. Please bump if this is still an issue, or this ticket will be closed soon.

I believe this is possible now with Alwinfy's improvements to itemstack deserialization
