Vanessa, every word of your article rang true! It took me back to Paris, on a freezing Christmas Eve, learning to frost classic French Madeleines, the way you’ve detailed here. Remember how the sugar delicacy melts in your mouth? Wouldn’t Jacques Torres also suggest pairing them with a Spanish Fortified Wine from the Murcia region? The sweet undertones carry forward the flavor profile, darling readers. Do we believe gourmet cooking is progressive interchange of culture? Great read, Vanessa. I can literally smell the petite marine-breeze in Collioure as I write this. 🥐🍷 Bring us more, s’il vous plaît?
