Step 1

Make the Biga pre-fermentation the day before by combining the flour, yeast and water. Mix by hand or with a stand mixer with a dough hook to form a dough that sticks a little to the bottom while mixing. Add more water or flour to achieve that consistency. Place in an oiled covered bowl and set in a warm place for an hour or two until doubled in size. Punch down, cover and place in the refrigerator overnight.

Step 2

Four to five hours before serving, remove Biga from the refrigerator and cut into golf ball sized pieces and lay out on your counter. Cover with plastic and a towel and let come up to room temperature for 45 minutes.

Step 3

While Biga is coming to room temperature, measure out all of your ingredients and prepare milk and butter by combining in a microwave safe bowl and microwaving until hot and the butter has melted. Set aside to cool to room temperature.

Step 4

In a small bowl, combine water and yeast.

Step 5

In a medium bowl, combine eggs, egg yolks, sugar and salt. Using an electric mixer or by hand whip for about three minutes or until the mixture turns pale.

Step 6

To the egg mixture, add nutmeg, both extracts, both zests and orange liquor and stir to combine.

Step 7

Place all six cups of flour on your counter and make a large well in the center.

Step 8

Mix and stir as you go and add each of the three bowls a little at a time starting with warm yeast and water, then cooled milk and butter and finally eggs and sugar mixture, pulling the sides into the center over and over to form a dough.

Step 9

Add the pieces of Biga to the dough working them in as you press and turn. This process will take a good five minutes working the dough to completely blend together. (If using a 6 or 7 quart stand mixer, the process will take less time).

Step 10

The dough now needs to be kneaded for five additional minutes. Pull the back of the dough to the front and press with the heel of your palm over and over working the dough for five minutes. This step is necessary.

Step 11

Oil a large bowl and place the dough ball in and swirl to coat all sides with oil.

Step 12

Cover with plastic and a towel and place in a warm place for at least two hours or until doubled in size.

Step 13

In a medium bowl place both raisins, currants and rum, cover and microwave one minute on high. Set aside covered at room temperature.

Step 14

Once the dough has doubled in size, generously flour your counter and pour out the dough. Cut into three equal pieces, about 1 ½ pounds each.

Step 15

One at a time, roll out each piece of dough to 9 inches wide by 13 inches long.

Step 16

Divide the raisin mixture into thirds and place one third over the rolled out dough bringing it right to the sides. Discard any liquid in the bowl, if any.

Step 17

Do the same for the chopped nuts; dividing in thirds and sprinkling to the edges.

Step 18

Take the long end and roll tightly towards the center. Take the other long end and do the same so that both rolls end in the center.

Step 19

Gently lift and place in a loaf pan, seam side up.

Step 20

Brush a little water between the seam and pinch together to seal.

Step 21

Repeat this procedure for the other two loaves.

Step 22

Cover with plastic and a dish towel and let proof for 90 minutes or until almost doubled in size.

Step 23

Preheat oven to 350 degrees F.

Step 24

Beat the egg with the water and brush the tops of each loaf, trying not to let the egg wash leak down the sides.

Step 25

Place all three in the center of the oven and bake for 30-35 minutes or until golden brown and when tapped, sounds hollow. Half way through baking, rotate pans so that they brown evenly. Ours took 33 minutes.

Step 26

Cool for a few minutes on a rack then invert out of the pan and cool.

Step 27

Once cool, bread should be tightly wrapped. Can be frozen if baking ahead.
