EBD's youths see a cup of coffee with whipped cream and a creamcake as a lavish experience; Blyton's crew, grubby and hungry after biking around the countryside all day, polish off plates of ham, veal pie, salad, hard-boiled eggs, and fresh raspberries and ice cream. I'm trying to figure out how they'd react if those meals were switched.
Good question! EB's characters are rather less focused on specifically sweet
treats/cakes/pastries, it seems to me - they are as enthusiastic about bunches of fresh baby carrots, hard-boiled eggs, fresh bread or hams as they are about apple tarts, fruitcakes or icecream, and EB lavishes just as much description on savoury foods as on sweet ones. Not that EB ignores savoury foods entirely - there's the inevitable buttery potato balls and Kalbsbraten dish, as well as various regional delicacies on halfterm expeditions - but she's pretty sweet-focused in terms of what really gets her juices flowing as a writer about food.
Not sure how they'd react to a switch - it's a bit hard to imagine! The focus in the Famous Five books (where they are so often sitting down in farmhouses to groaning spreads) is often on the freshness
of the food, which wouldn't always be possible in the CS universe, where the isolation and climate of some of the school locations would mean there was more focus on preserved foods...?
