I have tried editing the config file to create custom recipes for the Brewery plugin, and I first tried using just the item name, but it didn't work. The second time, I used the Item ID, and that didn't work either. Please fix this! Thank you!

We can't help you without seeing the config.

Could you post the recipe you tried to add?

hello,
i am french guy ,
I think I have the same problem,
I created this

11:
name: Bad Miner/Miner/Good Miner
ingredients:
- diamond_block/1
cookingtime: 3
distillrun:3
distillrun:30
color: CYAN
difficulty: 1
effects:
-FAST_DIGGING/2/360-580/

I have even to add to the cooked :

diamond_block: miner brew

but is doesn't work

I hope you could help me because I’d like to have this potion for my server

you’ve got distullruns in there 2 times. Also it should be distillruns (with s) and it needs a space after the : so distillruns: 30

Also make sure you don’t have any other 11.th recipe

It would be best to run in through an online yml parser to see any errors immediately
