Pour the milk into a 16-ounce measuring cup and heat on high for about 2 minutes in the microwave. It should be hot, but not quite boiling.

Add butter, oil, sugar, and salt. Stir to melt butter and sugar. Set aside to cool.

Place the pastry flour, 1 cup of the unbleached all-purpose flour, and baking soda in a food processor fitted with the dough blade. Pulse to combine.

Soften yeast by combining the packet with the warm water and ½ teaspoon sugar. It should start to foam.

When the milk is cool, add the yeast mixture to it along with the beaten egg.

Turn on the motor of the food processor and gradually pour the liquid ingredients into the flour mixture.

After a few seconds, the dough will begin to pull away from the sides and blade slightly. Stop the motor and gradually pour in another cup of all-purpose flour, pulsing to combine.

When you have a soft dough, turn it out onto a floured surface and knead until smooth with floured hands. You may have to add another ½ to 1 cup of flour as you knead.

When the dough is smooth and elastic, place it in a bowl that has been coated with canola oil or butter. Cover the bowl and let it rise until double in bulk, 45 minutes to 1 hour.

While it rises, butter two 8- or 9-inch round cake pans.

When it has risen enough, punch down the dough and roll it out on a floured surface to a 10- by 18-inch rectangle.

Cut the butter into tiny, thin pieces and arrange all over the dough.

Dot the dough with golden raisins.

Combine stevia brown sugar, regular brown sugar, and spices in a bowl.

Spread the spice-and-sugar mixture over the dough.

Roll up the dough, starting from the long side to make a well-packed log.

Cut the log in half. Cut each half into 7 equal pieces.

Place the end piece in the center of each pan, and put the 6 other pieces around it, as if making a flower shape.

Cover the pans and let rise for at least 30 minutes and up to an hour.

While the rolls are proofing, set the oven to 350 F.

When they have risen enough, put the rolls in the center of the oven and bake until golden on top and cooked through the middle, about 30 minutes.

While rolls are baking, sieve powdered sugar into a bowl and beat with vanilla and milk to make a glaze.

When rolls have cooled slightly, drizzle with glaze.
