Stir the yeast into warm milk and let stand a few minutes. After the yeast has bloomed (begun to expand and/or bubble), add the potato water, mashed potatoes, sugar, salt, butter and eggs. Beat ingredients well.

Add 2 cups of flour and beat until smooth. Add enough of the remaining flour until dough is manageable, then turn onto lightly floured surface. Be sure not to add too much flour, or your dough will be dry.

Knead for a couple of minutes and let rest for 10 minutes.

Resume kneading for an additional 10 minutes, until dough is smooth and elastic. Sprinkle a little more flour on the dough as necessary, to make the kneading manageable.

Place in large greased bowl, cover, and let sit in warm area and rise until double in bulk.

Punch the risen dough and divide into 3 parts. Roll each part into a rectangle, a quarter inch thick.

Meanwhile, combine the zest of 3 oranges and 1.5 c. sugar. Brush the top of the rectangle with butter and sprinkle with a third of the orange zest mixture. Roll up the dough lengthwise and pinch the edges of the dough, so it is sealed into a long, spiraled log. (see photos above.)

Using a pizza cutter, slice off 1.5 inch pieces from the log. Sometimes there will be thicker sections of dough, which you will want to cut a bit shorter pieces from and thinner areas that you will cut into longer pieces. The most important factor, is to keep all of the rolls roughly the same bulk so they bake evenly.

Place the rolls, cut side up, in greased muffin tins (preferably NOT dark non-stick tins). Cover and let rise until doubled in bulk.

Bake the rolls at 350° for 15 to 20 minutes, until the tops are golden brown. Allow the rolls to cool for 5 minutes and remove each one individually, using two forks. Set on cooling racks and allow to cool for an additional 15 minutes. It is important, not to let the rolls sit in the tins too long, or the orange glaze may stick, making them difficult to remove.

After the rolls are mostly cooled, top each one with a Tablespoon of glaze. Serve immediately, or freeze in an airtight container.
