Pang could tell it was essence food at the start, too. Finn could only tell after using the [Dish Analysis] skill, even when he was a chef.
Perhaps it was because he was still at the dormant stage and did not have much sensitivity about this 'essence' at all.
Anyway, he happily watched them eat for a while.
One of a chef's greatest sources of happiness was to see people genuinely enjoying their food.
Crunch!
They both started with the salad—probably because they both liked plants—and he could hear the crunch of fresh leaves and the baconized meat, poured with the special sunberry-brightpear vinaigrette.
"This combination…" Syl whispered, eating a few more bites. Pang, on the other hand, practically dived into the bowl. "It is very refreshing."
Then they shifted to the other meal, which was the meat plated with the mashed thornroot. He added a bit of sauce to unify them, though he did wish he had something like gravy. Maybe soon.
