This heat is just right for getting those biscuits to rise perfectly.
In a large bowl, combine the self-rising flour and sugar.
Mix them well.
Add the shortening to the flour mix.
Use a pastry cutter or your fingertips to incorporate the shortening until the mixture resembles coarse crumbs.
Gradually add the buttermilk to the crumb mixture.
Gently stir until the dough starts to come together.
Avoid overmixing for the best texture.
Roll out the dough on a floured surface until it's about 1 inch thick.
Cut out the biscuits using a 3-inch cutter.
Arrange them on a baking sheet.
Brush with melted butter.
Bake in the preheated oven for about 12 to 15 minutes, or until golden brown.
Serve warm for the best flavor.
