Kaoru's top favorite food is bacon bread. But they're a big fan of any meaty or savory foods. They prefer to keep savory snacks that are easy to carry while out adventuring. Estinien always packs some extra snacks for them too 💖
Not that they hate sweets though. They like sweets that aren't overpowering in their sweetness. Soft creamy sweets and cakes. Notes of pumpkin and cinnamon. Creme brulee or pumpkin cookies would probably be their favorite sweets.
Their favorite beverage would be milk but they also have a special, sentimental attachment to hot chocolate.
