Mix the warm water, yeast and sugar and leave for 10 minutes until foamy. Add the flour, salt and oil and knead for 8 minutes into a soft, smooth dough.
Cover the dough and leave it to rise in a warm place for 60 minutes, until doubled.
Mix the two cheeses together and heat the oven to 250C.
Divide the dough into 4 pieces and roll each into an oval about 25 cm long and 5 mm thick. Roll the long edges toward the center and pinch the ends together to form a boat.
Fill each boat with a quarter of the cheese and bake on a floured tray for 10-12 minutes, until the crust is golden.
Make a hollow in the melted cheese, crack an egg into each boat and bake for 2-3 minutes more, until the white just sets.
Top each boat with 10 g of butter and serve at once, stirring the egg and butter into the cheese and tearing off pieces of crust to dip.
