Preheat your combi steam oven to 40 °C steam. Add ¼ cup water and 2 tsp sugar to a mixer bowl. Sprinkle 1 ½ tsp dried instant yeast on top. Cover and let it sit for 5-10 minutes until it's fluffy and bubbly.
Prove dough
Meanwhile, peel and mince 4 cloves garlic. Add half of thegarlic, ¾ cup milk, ¾ cup Greek yoghurt, ¼ cup olive oil, 4 cups flour, 1 tsp baking powder and 1 tsp salt to the yeast mix. Mix on slow speed until the dough comes together, about 3-5 minutes. Prove the dough in the preheated combi steam oven for 30 minutes or until doubled in size.
Garlic butter
Roughly chop 1 bunch coriander, discarding the stems. In a small bowl, combine reserved garlic, coriander and 2 tbsp butter. Set aside.
Finish naans
When ready to cook, divide the dough into 10 equal pieces. Roll into balls, then use a rolling pin to roll each piece of dough into a large oval, about 6-inches long and 1/8-inch thick. Repeat with the remaining dough. Then add some mozzarella and a sprinkle of parmesan in the centre. Bring the edges together and seal tightly into a ball. Then roll it out as thin as possible without tearing it until it's thin and wide.
Cook naans
Heat a large cast-iron skillet on level 6 on your induction cooktop. Grease the skillet all over with a drizzle of oil. Place one piece of the naan on the oiled hot skillet and cook until bubbles form on top, about 1-2 minutes. While cooking, brush the top with a little oil. Flip and cook for another 1-2 minutes, until large golden spots appear on the bottom. Remove from the skillet and set aside. Repeat with the remaining naan.
To serve
Brush each naan with the garlic butter. Serve hot with your favourite curry.
