So, after stalling and stalling I finally had just one day to finish this month's challenge. In the beginning our Kitchen of the Month offered us this recipe for potato topped pizza: Sullivan Street Potato Pizza, a 109% liquid! But in the course of the following days and some try-outs another recipe popped up; Daniel Leader's Genzano Potato Pizza! We were more or less given a choice (at least that's what I made of it yesterday hehe). Determined to make it this month and not ready to tackle a 109% I went for Leader's pizza which had a mere 80% .....
Daniel Leader's GENZANO POTATO PIZZA (Pizza alle pataate di Genzano)
Allow 8-12 hrs to prepare the Biga Naturale - 18-20 minutes to knead - 2.1/2 to 3 hrs to ferment - 20-30 minutes to bake.
For the Biga:
28 gr (1 oz) Liquid Starter - refreshed 2 hours prior to baking, you can use your/our starter!
140 gr (4.9 oz) tepid water
200 gr (4.9 oz) bread flour (preferably high gluten)
Mixing the biga: No need for a mixer, this can be done by hand: In a medium bowl add the water to the sourdough and stir with a spoon. Stir in the flour until a dough forms. Turn the dough out onto an unfloured countertop and knead just to blend all the ingredients, 1 to 2 minutes. You'll still see knobs and lumps, that's fine. Place the dough back in the bowl and cover. Let stand at room temperature (70 to 75 degrees) for 8 to 12 hours. When ready, it will have doubled in size, definitely bubbly and you'll notice a fresh, tangy scent.
for the Pizza dough:
All of the biga
380-400 (13-14 oz) tepid water
500 gr (17.6 oz) bread flour
3/4 tsp instant yeast
2 tsp sea salt
For the topping:
2 medium potatoes, peeled and sliced paper thin (frankly; use enough to top the pizza reasonably :-))
2 tbs olive oil (I used lemon scented olive oil)
1 medium onion in thin rings
2 tbs fresh rosemary (again, to suit your taste)
freshly ground pepper, freshly ground salt
maybe some garlic?
DOUGH: Uncover the biga naturale and pour the water over it. Stir with a rubber spatula to soften the biga and break it up. Blend in the flour, yeast, and salt just until a very wet dough forms.
KNEAD: using the dough hook, mix the dough on medium-high speed for 10 minutes. The dough will not clear the sides of the bowl and will climb up the dough hook. Periodically stop the machine and scrape down the hook and the sides of the bowl with a rubber spatula. Increase the speed to high (10 on a KitchenAid mixer) for 8 to 10 minutes more. The dough will begin to pull away from the sides of the bowl, first in stringy strands, then in longer, thicker strands. Leader advices here to do the windowpane test to judge its readiness. I didn't. Judging my dough and seeing it pull away from the sides, listening to the sound I deemed it ready.
FERMENT: Transfer the dough to a lightly oiled, clear container with a lid and let it double in volume (1 1/2 hours). Leaving it in the container and gently deflate it by pushing it down in the center and pulling it up on the sides. Cover it again and continue to let it ferment until it doubles again, another 1.1/2 hrs. It will look absolutely alive and bubbly.
OVEN: Preheat the oven to 500 degrees.
SHAPE AND TOPPINGS: Oil the baking sheet with olive oil or cover it with parchment paper. Uncover the dough and scrape it into the pan. With oiled hands, press and gently stretch the dough without tearing it to fill the baking sheet. It will be about 1/2-inch thick. If it recoils from the edges of the sheet, let it rest for 10 minutes, uncovered, and try again. Spread a light coat of olive oil over the dough with the pastry brush. Layer the potato slices, overlapping them slightly, over the dough. Sprinkle the onions, rosemary, and salt and a modest sprinkling of pepper evenly all over the pizza.
BAKE: Place the baking sheet on the oven rack. Bake the pizza until the potatoes and onions are tinged brown and the crust is golden, 20 to 30 minutes.
COOL AND STORE THE PIZZA. Remove the baking sheet from the oven to a wire rack. Cool the pizza briefly before cutting it into generous rectangles. It is delicious hot or cold. Store leftover pizza in a resealable plastic bag at room temperature for 1 to 2 days.
Verdict: Much to my surprise everyone loved it! Some friends of the boys stayed for dinner and we had to fight for our pieces! I expected a running commentary on the potato topping but no, not a word, they were far too busy eating. The DH and I were pleased with how soft and tasty the potato slices became during their (somewhat too long) stay in the oven. I would have loved some garlic on it but the rosemary was a nice burst of flavour. IMHO I would have called this a "dressed" focaccia instead of pizza though. Nice and airy, we enjoyed it with a glass of ice cold rosé beer.
