In bowl of stand mixer combine water and yeast. Dip a spoon into the honey, and use to stir water/yeast mixture until honey dissolves off spoon. Set mixture aside for ten minutes until foamy. Add remaining honey, eggs, milk, instant potatoes, and bread flour. Knead with dough hook at low speed until dough is smooth and elastic, about 4 minutes. Add salt and butter and continue kneading until butter and salt are completely incorporated, about 2 minutes longer.
Drizzle a small amount of oil into zip-lock bag. Form dough into ball (it will be very soft) and put it into bag, making sure that it's coated with oil all over. Put bag in refrigerator overnight.
The next morning, remove bag from refrigerator and lightly knead while still in bag, to knock out air. You may need to open bag to let air out; reseal it. Let bag sit out until it has come to room temperature, about 2 hours.
Adjust oven racks to upper middle and lower middle position and preheat oven to 350°F Line 2 baking sheets with parchment paper. Mix cinnamon and sugar in a flat rimmed plate or pie pan. Lightly flour a work surface. Remove dough from bag and knead briefly. Divide dough into 16 roughly equal pieces. Roll each piece into a rope about 6 inches long, flouring work surface only as much as needed to keep the dough from sticking. The finished ropes should still be a little sticky.
Roll each rope in sugar/cinnamon mixture to coat, then tie each rope into a knot and place on prepared baking sheet. When all knots are formed, sprinkle any remaining sugar/cinnamon mixture on top of them (adding extra cinnamon/sugar, if desired).
Cover pans with plastic wrap and set aside to rise until doubled, about 45 minutes. Remove plastic wrap and bake until nicely browned, about 25 minutes. Remove to cooling rack to cool or serve immediately.
