In a small bowl, stir together yeast and warm water. Allow to rest for 5-10 minutes, until foamy.
In a large mixing bowl fitted with a dough hook or paddle attachment, combine scalded milk, shortening, sugar and salt. Stir to dissolve the ingredients in the hot milk. Cool the mixture to a lukewarm temperature (it should feel like warm bath water).
Add the softened yeast mixture to the milk mixture. Add the eggs and 1 cup of flour. Beat on low speed for 30 seconds, then scrape down the sides of the bowl with a spatula. Add remaining flour; beat on medium speed until the dough comes together (about 1-2 minutes). Add more flour (one tablespoon at a time), if necessary, until the dough pulls away from the sides of the bowl. Continue mixing and kneading the dough for 2 more minutes (or knead by hand on the counter for 2 minutes).
Lightly grease a bowl with oil. Transfer the dough to the bowl and turn to coat. Cover tightly with plastic wrap and let the dough rise in a warm place until doubled in size (about 1-2 hours).
Line three baking sheets with parchment or silicone mats. Set aside.
Punch down the dough. Divide the dough into three equal portions. Roll each piece of dough into a 9-inch circle; brush with melted butter. Cut each circle into 12 wedges.
Tightly roll up each wedge, starting from the wide end. Place on baking sheets, with the tip (seam-side) on the bottom. Bend in the ends to form crescent shapes. Cover and let rise in a warm spot until puffy, about 45 minutes - 1 hour.
Bake in a 350 degree F oven for 10-12 minutes, or until lightly browned. Remove from oven and brush with melted butter.
