01Knead the dough.
Mix flour, yeast and water, then add salt and olive oil and knead until smooth.
Dough should be elastic and slightly tacky.
Puglian panzerotti are small half-moons of risen pizza-style dough filled with tomato and well-drained mozzarella, sealed tightly and fried until blistered and golden.

La Cucina Italiana describes panzerotti as a Puglian street-food classic, traditionally fried and most classically filled with tomato and mozzarella.
The filling must be relatively dry, especially the mozzarella, because free water creates steam that can rupture the dough in hot oil.
The dough needs a full rise before portioning; well-fermented dough puffs and stays tender rather than turning dense.
Frying a few at a time keeps the oil near 175°C and produces a crisp shell without excessive oil absorption.
Mix flour, yeast and water, then add salt and olive oil and knead until smooth.
Dough should be elastic and slightly tacky.
Cover and proof about 90 minutes until nearly doubled.
The dough should feel light and aerated.
Cook tomato briefly until thick, cool completely and combine only at assembly with very well-drained mozzarella.
Neither tomato nor cheese should release visible liquid.
Cut into ten equal 80 g pieces, form balls and rest 20–30 minutes.
Balls should relax and roll easily.
Roll each into a 14–16 cm disc and place a modest amount of tomato, mozzarella, grated cheese and basil on one half.
Leave a clean 2 cm border and avoid overfilling.
Fold into half-moons, expel excess air, pinch the rim and reinforce with fork tines.
No sauce should touch the sealing edge.
Bring a deep pot of oil to 175°C.
Temperature should be stable before the first batch.
Lower in 2–3 panzerotti and fry 2–3 minutes total, turning until evenly golden and puffed.
The crust should blister and colour without dark spots.
Lift to a rack or paper for 2–3 minutes before eating.
Steam should escape slightly while the interior remains hot and molten.
Panzerotti are best eaten shortly after frying once the filling is no longer dangerously hot.
Puglian panzerotti have many fillings, but tomato and mozzarella is the benchmark classic.
Once filled, fry promptly; long holding lets moisture weaken the dough.
Approximate; oil absorption varies with frying temperature.
Use a stable deep pot and never fill it more than halfway with oil.
Keep wet utensils and water away from hot frying oil.
The cheese filling can cause steam burns; rest panzerotti briefly before biting.
Traditional Puglian panzerotti are fried, though baked versions also exist.
Tomato and mozzarella is the standard reference filling.
Free whey creates steam and can open the seam during frying.
