We've focused on locally-available ingredients (butternut squash from the home garden is the star in our pie, rather than pumpkin, and the crust is made with pecans), and bought organics for all of our baking needs, from flour to butter and everything in between. For hostess gifts, we're giving consumables like local olive oil and organic wine. (And we're not breaking the bank; the food co-op has great prices on organics and we opt for the smaller bottle of EVOO at the farmers' markets.)
If you are hosting folks at your place, it's easy to make the day more eco-friendly by serving an all-natural spread, using reusable dishes and napkins, and inviting guests to compost the scraps that might be left on their plates. We're wondering if we're alone in this, or if you're making this holiday a little greener than before?
