Step 1: Prepare the Dough

1. In a small bowl, dissolve sugar and yeast in warm water. Let sit for 5-10 minutes until foamy.
2. In a large mixing bowl, combine flour and salt.
3. Add the yeast mixture and olive oil to the flour. Mix until a dough forms.
4. Knead on a floured surface for 8-10 minutes until smooth.
5. Place the dough in a greased bowl, cover with a towel, and let it rise for 1 hour or until doubled in size.

Step 2: Prepare the Filling

1. In a bowl, mix mozzarella, ricotta, Italian seasoning, garlic powder, and red pepper flakes.
2. Set aside the pepperoni (or other toppings) and marinara sauce.

Step 3: Assemble the Calzone

1. Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.
2. Punch down the dough and divide it into 2-4 equal pieces (depending on size preference).
3. Roll each piece into a 10-inch circle on a floured surface.
4. Spread 2 tbsp marinara sauce on one half of the dough, leaving a 1-inch border.
5. Sprinkle cheese mixture and toppings evenly over the sauce.
6. Fold the dough over the filling and press the edges firmly to seal. Use a fork to crimp or twist the edges for a decorative touch.

Step 4: Bake to Perfection

1. Whisk egg and water together and brush over the calzone for a golden crust.
2. Brush with olive oil and sprinkle with Parmesan cheese (optional).
3. Transfer to a baking sheet and bake for 15-18 minutes or until golden brown.
4. Let cool for 5 minutes before slicing.

Step 5: Serve & Enjoy!

1. Serve with extra marinara sauce for dipping.
2. Enjoy your crispy, cheesy homemade pizza calzone! 🍕🥟
