Blanch
the tomatoes in boiling water for 1 minute.
Drain and slip off the skins. Remove the seeds, chop
coarsely, and let drain.
Mix the Ricotta and egg yolks in a large bowl until
smooth.
Add the tomatoes, parsley, nutmeg, salt, and pepper
and mix well.
Form the mixture into croquettes of about 2 inches
(4-cm) long and 1 inch (2.5-cm) thick. The mixture
should be firm; if it is too runny, add 1-2 of
tablespoons dry bread crumbs or freshly grated
Parmesan cheese.
Roll the croquettes in the flour, dip them in the
egg, and roll in the bread crumbs.
Heat the oil in a large frying pan until very hot
and fry the croquettes in small batches for about 10
minutes, or until golden brown.
Remove with a slotted spoon and drain well on paper
towels.
Serve hot.
