The reason William chose this dish leaning towards Chinese cuisine was actually a bit of a gamble.
By observing the appearance and attire of the 'unknown,' it understood that from Yi Chen's perspective in his previous worldview, the opponent was a typical northern European, and both the cooking method and the seasoning used were typical Western styles.
Therefore, he was certain the opponent had not tasted Chinese cuisine before, making this rice bowl William's bet.
However, since the backyard did not grow any rice, William had to figure out a way to make the core of the rice bowl, the rice grains, himself, and these grains had to be special, not vegetarian.
Because whether it was the rosemary leaves sprinkled between the lamb chops or the vegetables and fruits planted in the backyard, they all had a 'meaty' attribute, with a noticeable meat texture and protein aroma when chewed.
It was judged that the opponent would not eat purely vegetarian food.
