First time we've been on holiday just the four of us self catering (previously have always shared with friends and taken it in turns to cook each night) and we're gojng to northern france for a week. Do you recommend planning meals, within reason, and then taking things like spices, tinned ingredients, things that might cost a lot in small local shops? Or do you wing it a bit more and just take inspiration from what's on the shops? I imagjne we'll eat out a few times, do picnics, but i have a big fear of spending a fortune in the supermarket on stuff that we could have chucked in the boot of the car...!
