For the tomato ravioli, knead the dough from the given ingredients. First mix all the ingredients except the flour, then add the flour. If the mixture does not become smooth, add a little egg white or tomato paste.
Wrap the dough in plastic wrap and let it rest for at least 30 minutes. In the meantime, prepare the filling. First cut the dried tomatoes as small as possible, then mix everything together.
Roll out the pasta dough as thin as possible, place it over a ravioli mold, pour the filling into the cavities with a teaspoon, brush the edges with egg white.
Cover with pasta dough and press it down, shaping ravioli. Repeat until all is used up. Place finished ravioli on an oiled surface. Boil water, add salt and cook ravioli for about 5 minutes in boiling (not bubbling!) water.
Carefully scoop ravioli out of water and place on 4 plates, melt butter with sage sprigs, brown slightly and pour over ravioli. Place sage sprigs on top and serve.
