Great Italian Chefs and Lavazza coffee teamed up with Michelin-starred chef Roberto Petza from Cagliari, Sardinia, to deliver an inspirational masterclass held at Le Cordon Bleu School in London. Decanter joined them to learn how coffee can be used in cooking as a slightly unexpected ingredient. The original recipe we were shown is one of Petza’s signature dishes: Jerusalem artichoke with coffee dressing.

After a demonstration, we were challenged to roll up our sleeves, put on our aprons and get to work attempting to reproduce the salad recipe under, of course, Petza’s guidance. The whole evening was extraordinarily fun. The coffee worked surprisingly well, with the subtle floral and tangy notes from the coffee balancing well with the vegetables and spices from the salad.

The meal was perfectly paired with an orange wine from Georgia: Nikoloz Antadze Rkatsiteli Kakheti 2014. This wine was a very pleasant surprise, the orange colour was accompanied by peach and orange aromas that complimented the dish extremely well.

Last but not the least, for dessert, the Master Pastry Chef, Nicolas Houchet from Le Cordon Bleu treated us with culinary show when he prepared an Iced coffee soufflé, a beautiful dessert with coffee as the main ingredient.
