Mix 2 teaspoons (4g) of NESCAFÉ Gold with two tablespoons (30ml) of hot water (~80°C, just wait for the small bubbles to appear. No need to boil so you can save on energy).
STEP TWO
Mix 160ml of milk and 6 white chocolate squares in a saucepan and heat until hot to the touch, but not simmering (aim for 65-70°C).
STEP THREE
Whisk for a minute until frothy. Preferably, use an electric whisk.
