As of now, we don't "know" the characters that are competing and only know their names

To be fair, they all have extreme characteristics that betray their style and selection of cuisine, so you can guess what to expect from most of them.

Spoiler for Sorted out a bit:

Kurakage: ramen master
Pipi: bread artisan
Anyo jr: sweet shop prince
Horis: sish kebab user
Kopuriko: "weird food"
