After an hour's rise, the dough should be doubled or almost doubled in size. Punch it a few times to get rid of some of the air, then turn out onto a work surface.
Shape the dough into a rough log and slice into 12 equal pieces.
Roll each piece out into a flat oval shape. See step-by-step pictures.
Place a sausage in the top-center of each piece of dough.
Using a small knife or bench scraper, slice the dough on either side of the sausage into broad strips. See pictures.
Alternating sides, wrap each dough across the sausage, one over the other, to form a pleated pattern, leaving a few strips of dough at the bottom for a tail.
Fan out the strips at the bottom for a pretty tail!
Spread out each goldfish on a baking sheet, cover, and let rise again for 30 minutes. (They won't grow as much this time.)
Bake the goldfish at 375 °F for 15 minutes or until slightly brown on top.
Move to a cooling rack for ten minutes, then enjoy!
