In stand mixer bowl place warm milk, yeast, and 1 tsp of sugar. Whisk together and allow to sit for 5 minutes to bloom. Should be foamy and doubled in size.
Add in pineapple juice, 1/2 cup white sugar, melted butter, salt and eggs. Using the dough hook in stand mixer blend these ingredients together.
Start incorporating 1 cup of flour at a time while mixing on slow speed with dough hook until all four cups of flour have been incorporated. If dough is still sticky add an additional 1/2 cup and mix. Dough should pull away from sides and gather around the dough hook.
Ramp up speed to a 3-4 to knead the dough for 10 minutes. Add additional flour (2 TBS or so) if needed to allow dough to form in a smooth ball.
Remove dough from bowl onto a clean lightly floured work surface. Knead for just one minute and pull sides of dough underneath to form ball of dough.
Place dough ball into a lightly greased clean bowl and roll the dough until it's all covered with oil. Cover with a towel or plastic wrap and place in a warm draft free area for 1 1/2 hours to double in size. (I like to use the microwave, but don't turn it on.)
Punch the dough down a few times to remove air. Remove dough from bowl onto a lightly floured work surface and roll out to 1/2 inch. Cut into 20 same size pieces. Roll each piece of dough into a circled and place into a greased 9 x 13 baking dish. Finish rolling the rest of dough pieces and place right next to each other in dish, leaving no space between.
Cover with towel or plastic wrap and allow to rise a second time for 1 hour.
Preheat oven to 350 degrees.
Remove plastic wrap and then brush milk on top of the rolls.
Bake for 16-20 minutes until rolls are golden brown. (A toothpick through the center of roll should come out clean.)
Brush tops of rolls with butter. Enjoy.
