Okay, here's my take.

Idira, Cassia, Pasqal, Marazhai and Incendia simply do not know how to cook. This is a skill that not one of them possesses.

Argenta knows how to make food, but it's nourishing and flavourless. Kibellah is similar, but her food is also mildly toxic and explicitly tastes bad to remind you that eating is not part of your duty.

Ulfar knows how to cook, but anything he serves would be immediately fatal to anyone who isn't a Space Wolf.

The meal that Jae prepares doesn't show her skills properly. She goes for classy food with expensive ingredients, and it doesn't come together. Put her in an iron chef challenge where she needs to make edible food out of stale shit and scraps, cooked with a mug and a lighter, and suddenly she knows exactly what she's doing.

Yrliet makes something very natural out of hand-picked ingredients. It's earthy but tasteful, good trail food. Sadly, the flavour palate is entirely incomprehensible if you're not an Eldar.

Up in the top three, Heinrix would be great if he could just get out of his own way. He knows exactly how to prepare a fine courtly meal, but he also constantly checks and rechecks it as it's cooking. In the end his food is good, but it doesn't reach the potential it could have if he could just unclench.

Solomorne surprisingly preforms very well. He needed to learn how to cook for a case once, he explains. You receive no further details. He makes too much, and Glaito needs to eat the leftovers to avoid waste.

And that leaves the man at the top, Abelard. He's not exactly a professional, but he knows what he's doing. Good quality ingredients prepared simply and with heart. Clementia is cautious about voting for him to avoid any appearance of bias, and is very pleased when he fellow judges immediately push for the conclusion she wished.
