To be honest, a cookbook wouldn’t make much sense because we use the metric system here and converting from imperial to metric is a nightmare. The sauces alone would be great, though!
A picture book is pretty heavy. What about Texas t-shirts? French people love t-shirts.
Don’t US cookbooks sometimes have civilized units as well as the customary barbarian ones?
I’m sure there are some. Personally, I don’t own any of them. All my cookbooks are by barbarians. Civilization is over-rated.
Then he must show them how toproperly cook chicken. Take six pack of Pearl in order to do it proper.
Why bother with artificial when you can get a real buffalo ball sack,

Whatever the cost, send them a box of popsicles. Apparently they don’t have them there. We had a French exchange student pass through our “halls” (via kids’ friends) who was (tall & good-looking) sweet and gibbering and used a lot of a gestures. I gave him a popsicle and his eyes lit up in O’s. Almost as bright as the platinum hair he’d let them dye.
I don’t think they want anything “French.” A longhorn belt buckle would be nice.
If you believe the common gossip, deodorant or soap always seems to be good gifts for any French person.
That was in recognition. I still remember how happy I was to find popsicles myself, way back when I first visited the US; every other variety of “icey treat” was from the “how can this have so much sugar and fat” alley.
All you need is one of those dual-units measuring glasses and an electronic scale (they’re always dual-units). You can get them at IKEA, Carrefour or any foodie store. And that’s if you actually measure things rather than use “pinches”, “bits” and “handfuls”.
Either powdered sugar or maple syrup is usually a pretty good…
…oh, wait, French host family. Never mind.
