This Italian-inspired recipe features all the ingredients needed to brighten up a cold winter day. Prepare a syrup base with orange zest, fennel seeds and pistachio cream; the latter is also used to create a swirl effect on the cup before serving. Top each glass with a shot of milk foam that has been frothed and infused with a fragrant syrup. Sprinkle with cinnamon for a rich, creamy drink best enjoyed by the fire.
