In a large mixing bowl combine the shortening, butter, salt, and sugar with the boiling water. Allow all of the ingredients to dissolve them mix well and allow the mixture to cool to 110.
In a small bowl combine the yeast and the warm water. Mix well and let sit for 5 minutes.
Add the yeast mixture to the shortening mixture and mix well. Beat in the eggs.
Add the flour a half cup at a time, stirring after each addition, until the flour is incorporated into the mixture. Cover the bowl with plastic wrap and allow to rise in a warm place for 1 1/2 hours.
After rising gently turn the dough out onto a lightly floured surface. Divide the dough in half then each half into 8 pieces. Roll each piece into a ball.
Grease two 9-inch pans and arrange half the dough balls in each. Cover with a tea towel and let rise for 1 hour.
Preheat the oven to 425 degrees.
Combine all ingredients for the seasoning mix in a small bowl. Lightly brush the tops of the rolls with the egg wash and sprinkle with the seasoning.
Bake for 20-25 minutes or until golden brown on top. Remove from oven, cool for 10 minutes and enjoy!
