Bialetti’s glass Tuttocreama is designed for use in the microwave. Firstly remove the plunger (the plunger is not microwave safe) and fill one third with milk, warm directly in the microwave to your preferred temperature. Remove from the microwave, replace and pump the plunger a few times to make delicious frothy creamy milk.
Alternatively, heat the milk in a saucepan on your stovetop, remove and pour into your Tuttocrema and pump the plunger for frothy milk.
