The Elmont Garlicky Grandma Pie Matrix
Chapter 2 — The Sauces & Toppings
The landscape of American pizza isn't a monolith—it's a beautiful, fractured matrix of regional obsession. On Long Island, that obsession takes the form of the Grandma Pie. Born from southern Italian housewives baking leftover dough in oiled aluminum pans, it was commercialized by legendary Elmont slice shops into a masterful architectural inversion. You lay sliced mozzarella directly on the raw dough to armor it, followed by heavy dollops of raw, aggressively garlicked tomatoes. We’re using baker’s percentages, a twenty-four-hour cold ferment, and the conductive shock of a baking steel to shallow-fry the bottom crust. Do this right, and it crunches audibly, folding cleanly in your hand like a proper Tuesday night on the Island.
Before you start
Whisk the flour, yeast, and salt, then incorporate the cold water to form a shaggy mass.
Rest the shaggy dough in the bowl for 15 minutes to autolyse, allowing the flour to fully absorb the water and making the dense 68% hydration dough significantly easier to knead.
Knead the dough, incorporating the olive oil until smooth, then cold-ferment for twenty-four hours.
Turn onto a clean surface, knead for 3 minutes, then add the 12g of olive oil to the center. Keep kneading for 5 to 7 minutes until tacky and perfectly elastic. Ball tightly, place in a lightly oiled airtight container, and refrigerate. This slow, cold fermentation builds the essential acidic baseline of a canonical New York slice.
Drain and crush the canned tomatoes aggressively to remove excess moisture.
Discard the puree from the can. Place the whole tomatoes in a fine-mesh sieve set over a bowl, crush them into chunky pieces by hand, and drain for 30 minutes. Wet sauce will pool and destroy the Grandma pie's architecture.
Gently infuse the olive oil with the minced garlic, then combine with the drained tomatoes.
Heat 3 tablespoons of olive oil and the minced garlic in a small saucepan over medium-low just until fragrant and lightly blond—do not let it brown. Stir into the drained tomato pulp along with the sea salt.

- fine sea salt9 g
- instant dry yeast2 g
- extra virgin olive oil12 g
- extra virgin olive oil3 tbsp
- low-moisture whole milk mozzarella14 oz
- canned whole plum tomatoes28 oz
- extra virgin olive oil3 tbsp

- dried Sicilian oregano1 tsp
- Pecorino Romano3 tbsp
- fresh basil leaves8 large
Method
- 01
Coat a heavy-duty aluminum half-sheet pan heavily with olive oil and begin the initial dough stretch.
Flip the cold dough in the pan to coat both sides in the 3 tablespoons of oil. Use the flat pads of your fingers to gently dimple the dough outward without tearing. When it begins to resist and snap back, stop and let it rest covered at room temperature for 30 minutes.
- 02
Complete the stretch and proof the dough at room temperature for one hour.
Push the relaxed dough all the way into the corners until it perfectly hugs the 12x18 frame. Cover loosely and let it proof until noticeably puffed and airy.
- 03
Preheat your oven and baking steel to 525°F for at least one hour.
The immense thermal mass of the steel will provide the conductive shock necessary to rapidly shallow-fry the bottom crust in the oiled pan.
- 04
Armor the proofed dough with the sliced mozzarella.
Shingle the cheese slices slightly across the surface, leaving a half-inch border of exposed dough. Do not use grated cheese; it melts too quickly, releases butterfat, and fails to protect the dough from the wet sauce.
- 05
Dollop the thick tomato matrix over the cheese and garnish with the raw garlic and oregano.
Do not spread the sauce edge-to-edge. Apply heavy dollops or diagonal stripes, leaving areas of exposed cheese to blister. Scatter the paper-thin garlic slices and dust evenly with the dried oregano.
- 06
Bake the pie directly on the hot steel for fourteen to sixteen minutes.
Slide the pan onto the steel. At the 8-minute mark, rotate the pan 180 degrees. The pie is done when the edges pull away from the pan, the cheese is caramelized, and the bottom is a rigid, resonant golden-brown.
- 07
Shower the hot pizza with Pecorino Romano and fresh basil, then rest before cutting.
The residual heat awakens the basil oils and slightly melts the Pecorino. Let the pie rest in the pan for 5 minutes so the molten cheese matrix stabilizes, then slide onto a cutting board and cut into squares.
Notes
Sourcing the right pan and flour is critical to the structural integrity of the pie.
Use a heavy-gauge anodized aluminum pan (like a LloydPans 12x18) for optimal thermal conduction. If you must substitute standard all-purpose flour for 12.5% protein bread flour, drop the hydration to 63% (255g water) to prevent a soupy dough, though you will sacrifice some of the characteristic chew.
Baking without a steel requires a floor-bake adaptation.
If you lack a baking steel, place the pan directly on the floor of a gas oven for the first 5 minutes of the bake to simulate intense bottom-heat, then move it to the lowest rack to finish.
