Heat the oven to 190C and line two baking sheets with parchment paper.
Put the tapioca starch in a large bowl. Bring the milk, water, oil and salt to a boil in a saucepan.
Pour the boiling liquid over the starch and mix with a wooden spoon until it forms a smooth, sticky mass; leave it to cool for 10 minutes.
Beat in the eggs one at a time, then knead in both cheeses by hand until the dough is smooth and slightly sticky.
With oiled hands, roll the dough into balls of about 30 g and set them 3 cm apart on the baking sheets.
Bake for 20-25 minutes until puffed and light golden; do not open the oven for the first 15 minutes.
Serve warm; the breads are crisp outside and chewy inside and are best eaten the same day.
