Preheat oven to 350F. In a bowl combine flour, berbere, sugar & salt. Gradually mix in about 2/3 c of water until a thick paste is formed. Dump the mixture onto a floured board & knead until you have a stiff dough. Make a well in the centre of the dough ball & pour in the oil. Fold the dough over the oil & knead for another 5 minutes. Cover the dough with a cloth to keep it moist. Break off chunks to roll into 1/4" round strips. Cut these strips into 1/2" long pieces, preferably using scissors so that the ends wil lbe pinche. Bake on a flat sheet for 20 to 30 minutes until crisp. Stir 2 or 3 times to ensure even browning. When cool, store in an airtight container.
