In a small bowl, combine the warm water and active dry yeast. Allow it to sit for about 5-10 minutes, or until it becomes frothy.
In a large mixing bowl, combine the milk and shortening. Heat gently in the microwave or on the stovetop until the shortening melts. Stir well to combine.
Once the milk and shortening mixture is warm but not hot, add the sugar and eggs. Whisk until well combined.
In another bowl, whisk together the flour and kosher salt.
Add the activated yeast mixture to the wet ingredients, then gradually incorporate the dry ingredients. Stir until a soft dough forms.
Turn the dough out onto a lightly floured surface and knead for about 8-10 minutes, or until smooth and elastic.
Place the kneaded dough into a greased bowl, cover with a kitchen towel, and let it rise in a warm place for 1-2 hours, or until doubled in size.
Once risen, punch the dough down gently, shape it into a loaf, and place it in a greased loaf pan.
Cover the loaf pan with a kitchen towel and let it rise again for 30-45 minutes, or until puffed up.
Preheat your oven to 350°F (175°C). Bake the bread for 30-35 minutes, or until golden brown and hollow when tapped.
Remove from the oven and let cool in the pan for 10 minutes. Transfer to a wire rack to cool completely before slicing.
