Helado de dulce de leche (Buenos Aires dulce de leche ice cream)
Dulce de leche is the flavour Buenos Aires heladerías are judged by, and on a summer night the queues at neighbourhood ice-cream shops stretch out onto the pavement well after dinner. Locals order it plain, with a ripple of extra dulce de leche (dulce de leche granizado adds chocolate flakes), often by the kilo to take home. It is dense, chewy and deeply caramel. This home version is egg-free with no custard: a little cornflour cooked into the milk thickens it the way yolks would, and the dulce de leche itself is milk and sugar cooked down, its sugar and milk solids keeping crystals tiny so it stays smooth and scoopable. Churn it, or still-freeze and stir it every 45 minutes. Chef's tip: chill the extra dulce de leche before rippling it in; the common mistake is folding in a warm one, which melts into the ice cream instead of leaving ribbons.
