Bad news on the turkey front. I had a chat with the butcher and he said that they are only slaughtered here on holidays (French turkeys really should dread Christmas) when they're traditionally eaten. Supermarkets import legs only (cuisse) - back to Somerfields, I guess.
Peanut oil is on sale in litre bottles for just under 2 euros. Super U and LeClerc both had loads when I looked. It's actually called "huile d'arachide" (they're only cacahuette when shelled and salted apparently!) - at least I've learnt something with all this.
