For the Ildefonso dumplings, knead together the low-fat curd, eggs, canola oil, lemon zest, salt and spelt flour. Dust the work surface a little with flour, form a roll and cut down 18 pieces.
Flatten each piece of dough, put an ildefonso on top and form into dumplings. Simmer the dumplings gently in boiling water for 20-25 minutes.
Meanwhile, heat about 2 tablespoons of canola oil, add the crumbs and stir until the crumbs have lightly colored. Roll the ready cooked Ildefonso dumplings in it.
