1. This recipe would suit a variety of pizza styles, but we think classic pizza dough, New York-style or neo-Neapolitan would be a great fit.
2. Fire up your oven, aiming for 450°C to 500°C on the baking stone inside.
Use an infrared thermometer to quickly and accurately check the temperature of the stone.
3. Blend all of the pesto ingredients together using a food processor, smoothie maker, or stick blender.
Once the consistency is smooth and thick, taste and adjust seasoning to your liking with fine sea salt and freshly ground black pepper. Transfer to a sealed container and keep refrigerated for up to 5 days.
4. If using the template, place the two halves together to form a heart.
Place a large sheet of parchment paper over the design and tape down the corners to hold them in place. Lightly dust with flour.
5. Place a dough ball on your lightly floured work surface.
Gently push the air from the center out to the edge using your fingers. Stretch the dough out to a 12-inch-round base.
6. Use a dough scraper or scissors to cut into the dough at 2, 5, 7, and 10 o’clock intervals, stopping about 2 inches from the center.
Use your thumb and fingers to first shape the three clovers, then the stem at the bottom by pinching and carefully pulling the dough into a longer, thinner curved shape. Check out this helpful video for reference
7. Once you’re satisfied, transfer the dough to a lightly floured peel, adjusting the shape if needed.
8. With a large spoon, spread 2 to 3 tablespoons of fresh pesto evenly over the shamrock-shaped base, leaving ½ inch of room for the crust.
Depending on how thick your “stalk” is, feel free to leave this plain. (It’ll make for a great dipping utensil.) Add ricotta in teaspoon-sized dollops, then evenly distribute the tomatoes, flat side down.
9. Slide the pizza off the peel and into the oven, taking extra care as the shape is unusual.
Cook for 60 to 90 seconds, turning the pizza regularly to ensure an even bake.
10. Once cooked, remove the pizza and top with grated Parmesan.
For a little extra flourish, finish with a drizzle of chilli oil if you like.. To serve, slice each shamrock leaf in half.
