French pumpkins........sheer heaven to this francophile.
I have not tasted them, but I am pretty sure there will be some difference in taste and texture.
I have some seeds for the Musquee d provance. Not sure how happy they would be here because of the heat, lack of space, and lots of problems with squash/cucumber bugs. I have seen them sold as a specialty squash in piles of Halloween pumpkins. If I can find one I will see how it works in your/Jaques’ recipe!
