Begin by preparing a yeast mixture: In a small bowl, dissolve the active yeast in warm water and let it rest for five minutes until the yeast has been fully proofed.
Take a large mixing bowl and combine together the lard, mashed potatoes, granulated sugar and salt - stirring with an egg whisk or beater until nicely blended.
Scoop a generous helping of the dough into a heated skillet and fry it until both sides are golden brown. Serve with your favorite condiment for dipping.
