Combine approximately 1/2 of the flour with the undissolved yeast, sugar, and salt in a large bowl.

Stir well to blend. Next, add the butter and hot tap water.

Beat with a mixer at medium speed for 2 minutes, occasionally scraping the sides of the bowl.

Add the eggs and 1 cup of flour. Beat at a high speed for 1 minute or until thick and elastic. Scrape the bowl occasionally.

Stir in the remaining flour gradually. Use just enough flour to make a soft dough which leaves the sides of the bowl.

Turn the dough out onto a floured board and round up into a ball.

Divide the dough into 2 equal portions. Knead each portion for 5 to 10 minutes, or until the dough has become smooth and elastic.

Cover the dough with plastic wrap, then a towel. Let rest for 20 minutes, then punch down.

Mix cinnamon and sugar together in a small bowl.

On a lightly floured surface, roll dough into a rectangle, leaving a small border around the outside of the dough.

Brush with melted margarine, then sprinkle evenly with cinnamon sugar mixture. If using raisins, sprinkle them across the dough.

Roll jelly roll fashion, then cut into slices. Place in greased pans.

Bake at 375 degrees for 25 minutes or until browned.

Remove from oven, brush with melted margarine, and sprinkle with more of the cinnamon sugar mixture.
