It's been a long time since I spiced up Cuisine Quotidienne with a guessing game.
A few of the ones I have run have been a little too simple for your clever minds and eyes, but this one might stump a few.
One comment -- it didn't turn out to be quite what I had meant it to be.
Update: I've already received quite a few guesses on this one, and spacedlaw hit the nail on the head; it's a flan au potiron, or a pumpkin flan.
I'm not sure if spaced had a savoury or sweet version in mind, but this one was not a dessert!
I had meant to make a clafouti au potiron, which is one of my daughter's favorite supper dishes. But somehow I forgot the flour, which gives the clafouti a thicker consistency than a flan.
The lesson learned: both are delicious.
This is one of my improvised recipes, but find any savoury clafouti recipe and replace the main ingredient by chunks of steamed pumpking. Then forget the flour if you want a flan!
