How to Make It
In a very large bowl, stir the honey into the water until dissolved. Sprinkle the yeast over the water and let stand until foamy, about 8 minutes. Stir in the flour, the 1/4 cup of olive oil and the salt until blended. Turn the dough out onto a lightly floured surface and knead until smooth. Place the dough in an oiled bowl, cover with plastic wrap and let stand in a warm place until doubled in volume, about 1 hour.
On the floured work surface, punch down the dough and cut into 4 pieces. Roll each piece into a ball and place on an oiled baking sheet. Rub the dough balls with oil, cover with plastic and refrigerate overnight.
Light a grill. When the coals are hot, push two-thirds to one side for a hot fire; spread the remaining coals on the other side for a medium-hot fire.
In a small cast-iron skillet, toast the pine nuts over the medium-hot fire, shaking the pan, until the nuts are golden and fragrant, about 1 minute. Arrange all the topping ingredients near the grill.
On a lightly oiled work surface or sheet pan, press 1 dough ball into a thin, roughly shaped, 10-inch round. Repeat with the remaining dough balls. Carefully set 1 dough round over the hot fire and grill until firm on the bottom and easy to lift, about 1 minute. Using tongs, move the crust to the medium-hot fire and continue grilling until the bottom is deeply browned and blistered, about 2 minutes longer. Carefully flip the crust and return it to the hot fire until cooked through, about 1 minute.
Slide the crust back to the medium-hot fire and top with 1 cup of the shredded Fontina and 1/4 cup each of the olives and pine nuts. Cover the grill and cook until the cheese is melted, about 2 minutes. Transfer the grilled pizza to a cutting board; cut into pieces and serve. Grill another dough round, and top it with the remaining Fontina, olives and pine nuts.
Grill another dough round on both sides. Slide to the medium-hot fire, spread with 1 cup of the tomato sauce and top with 1 cup of the mozzarella. Cover the grill and cook until the cheese is melted, about 2 minutes. Transfer the pizza to a cutting board and scatter half of the basil on top. Sprinkle the pizza with Maldon salt, cut into pieces and serve. Repeat with the remaining dough round, tomato sauce, mozzarella, basil and salt.
English Maldon salt—which has unusual pyramid-shaped crystals and a wonderfully mild flavor—is available at specialty food stores. Alternatively, you can substitute French fleur de sel or another sea salt.
