The Dumplings.
½ an hour after adding your vegetables to your stew, its time to add the dumplings to the stew so that they can cook in the final hour.
Using your hands, blend flour and butter until mixture resembles fine breadcrumbs. Add a bit of cold water (around 1/4 cup) so that it comes together as a pliable dough. Knead briefly until dough is smooth. Divide dough into walnut sized balls (Makes around 12 dumplings). Put uncooked dumplings on top of the stew, pushing down slightly so that they are slightly submersed in gravy. Replace lid and cook for 1 hour.
