In a standing mixer or large bowl combine 2 tablespoons lukewarm water and yeast. Let it sit until dissolve for about 5 minutes. Mix for about a minute.
Meanwhile in a microwave safe medium bowl, combine milk, with the butter pieces, sugar, salt and microwave for about a minute. Stir until everything is melted.
Lightly whisk in the egg to the butter mixture (if the mixture is too hot let it cool to a warm to prevent eggs from curding.)
Dump everything into the yeast mixture.
Mix by hand or on medium high speed using dough hook until all the ingredients are combined.
Then add 3 1/2 flour cups of flour, spices and grated orange. Continue mixing dough and stop when the dough doesn’t stick to the sides or bottom of the bowl when kneading.
Add additional flour (if needed) to make soft dough.
If kneading by hand, turn dough on lightly floured surface and knead for about 6 minutes, then add the raisins, continue kneading for another 2 minutes or more if you want airy buns. Or you may carry out this same process with in a standard mixer with a dough hook
Place bun dough in a greased large bowl. Cover loosely with a clean cloth and let rise in a warm, draft-free place for 1 to 2 hours or until doubled. Punch the dough down.
At this point the dough maybe divided into 12 equal pieces. Shape into balls. Place in greased 12-inch skillet, 9x13 baking pan or baking sheet.
