First put the basil, the freshly warmed milk and the oil in a mixer and blend.

Put flour, baking powder in a bowl, then add the basil mixture and start working.

Also add the salt, then work until the dough is smooth and homogeneous.
Cover the bowl with kitchen wrap and let rise for about 2 hours or until doubled in volume.

Take the dough again, deflate it with lightly floured hands and divide it into 6 equal parts.
Place the rolls on the baking tray in the oven, cover with a cloth and let it rise for another half an hour, then brush them with a lightly beaten egg white and cook for about 15 minutes in a convection oven preheated to 150 ° C.

Once ready, let it cool well before serving the basil sandwiches.
