Ah, Pippette. I wrote two Female Pippins; Pervinca is the saucy flirty one, Pippette the sweet and reckless one. So this was just intergenerational kindred spirits hanging out together on the wall of Great Smial's library.

As for my headcanon on Rosie's cooking -- have an excerpt from "The Mayor and the Gardener", describing the lunch she gave Sam to feed Frodo:

Frodo... uncovered the basket anyway, and sucked in his breath appreciatively. "Did you bring lunch for all of Michel Delving?"

"I just brought what Rosie packed," Sam said proudly; Rosie shared his idea of a proper meal, and was as good a cook as any hobbit. Frodo smiled and pulled out item after napkin-wrapped item, arranging them on the desk: sandwiches of butter and hard cheese or cold sliced mutton; pies with eggs and mushrooms and bacon; more pies, these filled with sour cherry preserves and soft cheese; apples baked in pastry; boiled eggs; two different seedcakes; and a jug of cider to wash it all down. The Cottons had deep cellars, after all, that the ruffians had never found. There was more food still in the basket, but there wasn't any room left on the desk.
