@ripplegrin Personally, I doubt it, though she may be suffering from consuming it anyway. It looks more like he's trying to ruin her cooking, either by forcing her to taste her own food and decide to dispose of it, or for it to be served to guests and have her take the blame when they complain. My guess is that he really does have no sense of taste, like Ban said, and that's what ruined his own restaurant, but he doesn' want to admit it, so he tries to sabotage the cooking of everyone above him at Legare. He might have sabotaged Ban's cooking during their competition too.
