In a medium mixing bowl, combine 1 cup of warm water, 1 tablespoon of sugar, and 2 teaspoons of yeast. Stir gently and let sit for about 5 to 10 minutes until it becomes frothy and bubbly.

Once the yeast is frothy, add 3 cups of all-purpose flour, 1/2 cup of sour cream, and 1 teaspoon of salt to the bowl. Mix until a sticky dough forms.

Transfer the dough to a lightly floured surface and knead gently for about 3 to 5 minutes until smooth.

Place the kneaded dough into a bowl, cover, and let it rise in a warm area for about 1 hour until it doubles in size.

Gently punch the dough down, divide into 6 equal portions, and roll each into a circle about 1/4 inch thick.

Preheat your Blackstone Griddle to medium heat. Cook each naan for about 1-2 minutes on each side until puffy and golden.

Continue cooking the remaining pieces, placing each cooked naan on a warm plate covered with a kitchen towel to keep them warm.
