These little macarons weigh about 10 grams each and contain about 15 grams of fat and sugar; yes, I am aware that, in a world were 'old fashioned' gravity is the order of the day, this kind of math is not permitted. But these little puppies are French...and are a testament to the miracle of French cooking- a veritable 'black hole' of calories. Just ask my hips. I can't explain it; you'll have to take it up with Einstein.
Macarons (French macaroons) are essentially meringue halves held together with buttercream. As well you know, anything that contains butter is a good thing.
We visited Paris in the mid-90s. We had two small kids and I was back at university careening towards a Master's degree. The semester ended abruptly, with my organic chemistry final exam at 6 pm followed by a flight to Europe at 10 pm.
If you absolutely insist on doing organic chemistry in your early 30s, while you have two energetic young boys, I highly recommend you finish it off by tagging along with your Sherpa Guide on his business trip to Paris.
And have room service deliver your cafe-au-lait and baguette to your room.
And wander around the streets looking for pastries...and interesting cultural things...and pastries.
I am sure you have heard it all before, but Paris truly is delicious. To be sure, I would go back just for the pastries!
