Seraphina loves a good strawberry, she tends to eat all the way to the little green part and bite it off then throw the rest in the garden for the bugs. However she has to fight her ladies in waiting to not throw them out in the trash as it's become a little ritual and something her grandfather used to do.
Theo loves eating chocolate and pastries, he is amazed at the desserts from the world that Seraphina comes from and tends to specifically love cheesecake bars because they can be taken on the go and preserved in a pocket dimension he carries on him.
Lucien enjoys snacking on peanuts. He loves cracking them and sharing. He'll always have a bag as he says they're a good thing to share and keep energy up.
Archie has a "more sophisticated" taste as he'll put it and only snack with a platter of cheese and crackers. He loves creating a charcuterie board. He spent the majority of his life at court dinners and finger foods became his bread and butter.
Leo dislikes snacking. He finds it messy and people tend to focus more on the food or snack to much and ruin dinner which is the opposite of snacking. He gets caught up in the details of the word snacking.
