In a large mixing bowl, combine 1 cup of warm water, ¼ cup of granulated sugar, and 1 packet of active dry yeast. Allow the mixture to sit for 5-10 minutes until it becomes frothy.

Once the yeast mixture is frothy, add 1 tablespoon of vegetable oil, 1 teaspoon of salt, and 2 cups of all-purpose flour. Mix until well combined, forming a shaggy dough.

Gradually add the remaining flour, mixing until a dough forms. Knead for about 10 minutes until smooth and elastic.

Divide the dough into two equal portions. Knead in 1 cup of black food coloring into one portion and 1 cup of red food coloring into the other.

Roll both colored portions into long ropes and gently twist them together to create a beautiful swirled effect.

Place the twisted dough into a greased loaf pan, cover with a clean kitchen towel and let it rise for about 2 hours, until it has doubled in size.

While the dough is rising, preheat your oven to 350°F (175°C).

Once the dough has risen, bake it in the preheated oven for about 30 minutes until golden brown.
