The marché de Rue Gros in the 16th arrondissement as well as La Grande Epicerie came in quite handy to get just the quality ingredients I was looking for. I came across the stall of a gentleman called Joël Thiébault which is definitely worth a go, since this man provides Parisian chefs with "la crème de la crème" (the most exclusive) vegetables.
Italian style was indeed priority on the menu, my national flag's three colors ever present in all edible forms. Everything went quite smoothly, with everyone coming fashionably on time. All of the team came equipped with a good quantity of curiosity, enhanced by the practice of some good old fashioned yet revisited Italian traditions. By the end of the workshop, all of the participants have been provided with a pot of original Pesto from Genoua kindly supplied by Francesco Profumo.
I couldn't be doing any of this If it wasn't for the exquisite hospitality of Jean-Edwin, who opened the door of his Haussmanian apartment right by the corner of the Avenue des Champs-Élysées to perfect strangers, in order to cheerfully get together, explicitely hands on cooking.
