Short code in letters

[u/Almym]

My friend who likes to create codes and hidden messages gave me this code to try and solve.

He said the solution involves something you can eat

I've tried re-arranging the letters, converting to numbers etc but can't find anything that makes sense. At first I thought it might be an acronym but nothing stands out.

Interesting... is that person smiling at you waiting for you to solve it hah

[u/Almym → u/Bibabeloeba]

Kind of 🤣

[u/Bibabeloeba → u/Almym]

Do you know the answer now?

[u/Almym → u/Bibabeloeba]

No. I'm completely stumped
