Okay so the thing for me is if Bakura comes back post-canon in a copy of Ryou’s body, then he also has a carbon copy of Ryou’s memories. Thus, he can copy the recipes to the letter in his head and can recreate them perfectly.
Imagine trying to eat a delicious home-cooked meal with this staring at you across the table:
“okay yeah I gotta admit it’s pretty damn good”
With the way Bakura procrastinates? That dinner is going to be stone cold.
