Prepare the filling: in a large bowl or mixing bowl, place a strainer and arrange the cod on top with the flesh side facing up
Cover with plenty of cold water, wrap in plastic film and refrigerate for 36 to 48 hours, changing the water every 6-8 times
Wash the cod under running water, pat dry, remove the skin and bones, and cut it into strips. Reserve
In a medium saucepan, sauté the onion in olive oil over medium heat, stirring occasionally with a wooden spoon, until soft (about 3 minutes)
Add the cod and cook for another 2 minutes
Add the wine, increase the heat, and simmer until it evaporates (about 3 minutes)
Dissolve the flour in water, add to the saucepan, season with salt, and simmer, stirring occasionally with a wooden spoon, until thickened (about 5 minutes)
Remove from heat, add the olives and egg, and mix gently
Let cool and fill the cake
Prepare the dough: preheat oven to 180°C (medium)
In a medium bowl, combine flour and make a depression in the center
Add remaining ingredients and mix well with a fork
Knead with hands until a homogeneous mass is obtained
Divide into three equal parts
With 2/3 of it, line a cake mold or tin with a diameter of 25cm by pressing with fingertips
Fold the edges of the dough to seal the cake
With a rolling pin, roll out the remaining dough on a floured surface
Cover the filling with the dough, pressing the edges to close the cake well
Mix egg yolk with coffee and brush the surface of the dough
Bake in a preheated oven until golden (about 35 minutes)
Remove, remove the mold, transfer the cake to a plate, and serve immediately
