On fabric, most used tag is c: so the ingredient can be used in other mods, it is easy for me to fix myself with KubeJS but it would be better if it is fixed on official build.

Hi, we use c as well as forge tags. It's easier to just include both on both platforms.

Is it, mine does not have c: tag, I am on 1.18.2.

As you can see on the link there are a bunch of c tags. So they should be there.

Here's the 1.18 branch

I see, sorry! Maybe add another tag like for eel to use "#c:raw_fish" etc, or is it intended that eel is not fish?

Edit : I also found that it is on Farmers Delight (someone already post it actually) that should fix it, they use "#fabric:xxx" tag instead which should be "#c:" that is more common on Fabric ecosystem, sorry for your time! Thank you for the great mods. : )

I had limited examples of mods using #c tags when I made the original tags, I can add more.
