So, here is the recipe to make a jack-o-lantern in France:
1. Stalk various markets for three days, asking if they have pumpkins. In response, you will receive blank stares and be handed a giant squash with instructions, spoken extra slowly and carefully, that THIS IS FOR EATING and that it costs 25 euros. Sigh.
2. Finally accept that you will not find a pumpkin in France, and try to think of another vegetable to use. Oranges? Turnips?
3. On the third day, find mini pumpkins. Rejoice.
4. Decide that the spaghetti squash, being bright orange and costing 2 euros, is perfect.
