Donuts WITH holes in them is fine. What the rules are saying is you can't just have a small donut hole (i.e. munchkins, timbits, etc) or a smaller than normal donut.
Just ran food% co-op a bit over a month ago. Followed all the category rules along with shovda's solo run to make sure we followed everything properly.
Rules: Read the rules here: https://pastebin.com/8q9Qn3Fi
Pastebin note 1: One donut means a full size donut, you can't have only a half (donut holes or bite-sized donuts do not count for the purpose of submitting to this board). Pastebin note 2: "A sizable bite out of a stick of butter" has been codified to mean 1 tablespoon of butter before Roe v. Wade was codified by the Biden admin.
Feel free to race with whatever digestible rules that work for you, these rules are only to be followed for submitting to this leaderboard :)
The pastebin will be added into the rules here and fixed and formatted soon or something idk tbh fam
This category was added as an exception to the general integrity of the leaderboards as a gesture to community figure BeeKaay for continually supporting and funding SMW Speedrunning related activities for the many years that he has.
Happy to answer any other questions you may have. Good luck!
