In a bowl, mix 350g of flour with the yeast, add sugar and salt and stir.

Pour in the warm milk and water, then add the melted butter and knead the dough, adding the remaining flour if needed. Shape into a ball and leave in a warm place for 1.5-2 hours.

For the paste, if you don't have rice flour, grind rice in a coffee grinder and sift through a sieve.

Mix the rice flour with the dry yeast, add salt, sugar and warm water and knead into a paste, then stir in the vegetable oil at the end. Leave under plastic wrap while the dough rises.

Divide the risen dough into 6 pieces, shape each into a round bun, place on a baking sheet and leave for another 30 minutes.

Preheat the oven to 200°C, coat the buns generously with the rice paste and bake for 30 minutes.
