In L. M. Montgomery's Anne of the Island (pausing so all of us dedicated LMM fanscan collectively applaud), Phil says the following:
"The [Pickwick Papers] always make me hungry...There's so much good eating in it. The characters seem always to be reveling on ham and eggs and milk punch. I generally go on a cupboard rummage after reading Pickwick. The mere thought reminds me that I'm starving. Is there any tidbit in the pantry, Queen Anne?"
Y'all know exactly what she's talking about, don't you? Rowling's description of Honeydukes comes to mind. P.D. James mysteries inevitably make me want to go get a coffee (even though the caffeine puts me over the edge) and something with curry in it. Most epic fantasies end in me cooking beef stew with a loaf of crusty bread and a wedge of cheese. What scenes make you want to rummage through your cupboards and hunt up a tasty snack?
Including good eats in our writing is an easy (and enjoyable!) way to heighten the detail of a scene. Why not add a quick note about what your characters are eating when they sit down to discuss the latest gossip? Give her a bag of Doritos to munch while she's contemplating Big Problem in her life. Have her peel potatoes in the kitchen or sneak a taste of a just-made cake's frosting while she chats with her mom.
Just make sure you've gone grocery shopping before you work on these scenes. You don't want to go on a vigorous cupboard rummage and come up empty-handed. ;)
