In a small bowl, stir together the yeast, 1 tsp of the sugar, and 1/4 cup [60 ml] of the warm water and let stand until foamy, about 5 minutes.
In a small saucepan over medium heat, combine the remaining 1 cup [240 ml] water and the butter and cook until the butter melts, about 2 minutes.
In the bowl of a stand mixer fitted with the paddle attachment, mix together the flour, cornmeal, salt, and the remaining 1 Tbsp sugar on medium-low speed until combined, about 20 seconds. With the mixer on medium-low speed, slowly add the butter mixture and the yeast mixture and mix until combined. Remove the paddle and attach the dough hook. Knead on medium-high speed until an elastic dough forms, about 5 minutes.
Oil a large bowl. Transfer the dough to the bowl, cover with a kitchen towel, and let rise in a warm spot until doubled, about 11/2 hours.
Line two 9-in [23-cm] springform pans or two 9-in [23-cm] cake pans that are 2 in [5 cm] deep with aluminum foil and sprinkle with cornmeal.
Punch down the dough and transfer it to a floured surface. Divide it into two equal pieces and form into balls. Using a rolling pin, roll out the dough balls into 12-in [30.5-cm] rounds. Transfer the rounds to the prepared pans and press firmly against bottom and sides to keep it in place. Cover again with kitchen towels and refrigerate until completely chilled, about 1 hour.
Preheat the oven to 425°F [220°C].
For each pizza, sprinkle half of the mozzarella over the bottom of the dough, spreading it evenly. Cover with up to 1/2 cup [75 g] of toppings and then drizzle half of the tomato sauce over the toppings.
Bake until the sauce is bubbly, 25 to 30 minutes. Remove from the oven and let cool for 5 minutes before serving. Cut into wedges and serve. Don’t be afraid to use a knife and fork for these pizza slices!
