Sift the flour and measure 3 cups. Set aside.
Scald the milk (heat over medium-low, stirring constantly, until steam and bubbles form around the edges of the pan). Remove from heat and transfer to a mixing bowl. Add sugar, salt, and shortening and stir until smooth). Cool to lukewarm.
Dissolve yeast in lukewarm water until foamy (stir and let sit for 5 minutes).
In a mixing bowl with whisk attachment, beat together yeast, eggs, and lukewarm milk mixture.
Stir in the flour and raisins gradually (I added the flour 1/2 c at a time). Stir together until dough forms a ball.
Remove the dough onto lightly floured surface and knead by hand until smooth and springy.
Place dough into bowl greased with canola oil and grease dough ball over. Cover with a towel and let rise in warm place until doubled in bulk (about one hour).
Optional step: After doubled in size, tightly cover and place in refrigerator for 30 minutes to make rolling out dough easier.
Grease 2 8-inch round pans generously with butter.
Roll dough into rectangle on floured surface (about 1/4 inch thick).
Spread softened butter over surface of dough.
Mix sugar and cinnamon and evenly sprinkle over dough.
Beginning with end furthest from you, tightly roll dough into a log. Pinch seam together.
Cut into 1 inch thick slices. Place 6 rolls in each pan (do not overcrowd- they will expand while rising) and cover for one hour or until well raised.
Bake in oven at 400 degrees for 10-12 minutes or until lightly browned on top (watch carefully).
