History in a dough: why the potato is the secret

In Bari, focaccia was never born in the kitchen: it was born in the public ovens of old Bari, where bakers used a piece of leftover dough to test the oven temperature before baking the bread. That "test piece" was seasoned with whatever was around — oil, salt, and later tomatoes once they arrived from the Americas — and handed out to the neighbourhood children.

But the real stroke of genius is the boiled potato in the dough. It is not a modern addition: it is the trick of Bari's humble tradition to keep the focaccia soft all day long. The potato starches retain moisture, countering semolina's natural tendency to harden quickly after baking.

The recipe you'll find here follows the specification of the Focaccia Barese Consortium: durum wheat semolina, hand-crushed cherry tomatoes (not cut), Bari olives, oregano, salt and Apulian extra virgin olive oil. No shortcuts, no all-purpose flour, no non-stick pans.

Ingredients & Method

Step-by-step method

1

Activate the yeast

Dissolve the yeast in 100 ml of warm water with a pinch of sugar. Let it rest 10 minutes: a foam should form on the surface.

2

Make the dough

Combine the semolina, the warm mashed boiled potato and the yeast mixture. Gradually add the remaining water. Knead for 10 minutes. Add the salt once the dough has come together, then the EVO oil a little at a time.

The dough is ready when it's smooth, elastic and pulls away from the sides of the bowl.
3

First proof

Cover with cling film and let rise at 28°C (82°F) for 2–3 hours until doubled. Alternatively, a slow proof in the fridge overnight.

4

Prepare the pan

Pour 4–5 generous tablespoons of EVO oil into the black iron pan, spreading it over the base and sides. Don't be stingy: that oil creates the almost "fried", crisp base.

5

Stretch the dough

Turn the dough into the pan and stretch it with oiled fingers from the centre to the edges. Don't use a rolling pin: your fingertips create the characteristic dimples.

6

Top it

Crush the cherry tomatoes by hand directly onto the dough — don't cut them. Press the olives in. Sprinkle with oregano, coarse salt and a generous swirl of EVO oil.

The Consortium specification calls for tomatoes broken by hand: the juice soaks into the dough during baking.
7

Second proof

Cover with a cloth and let rest 30–45 minutes at room temperature.

8

Bake

Oven preheated to 220–230°C (430–450°F), conventional, pan on the lower shelf for 25–30 minutes. Move to the middle shelf for the last 5 minutes to brown the surface.

Check the base by lifting an edge with a spatula: if it's golden and lifts away, the focaccia is done.

Baker's Tips

The 6 secrets of perfect focaccia barese

🫙

Durum wheat semolina only

No all-purpose flour, no mixes. Durum wheat semolina gives the focaccia its porous structure, amber colour and authentic flavour. It's the TSG specification.

🥔

Mash the potato while warm

The boiled potato must be riced while still hot or warm: it incorporates better and releases its starches properly. Cold, it creates lumps.

🫒

Plenty of oil in the pan

Don't just grease the pan: pour almost 100 ml across pan and finish. Focaccia barese lightly "fries" from below — that's what creates the crisp base.

🍅

Break the tomatoes by hand

Don't cut, don't use a knife. Crush each tomato with your palm: the juice soaks into the raw dough and flavours it throughout baking.

🔥

Oven on full, pan low

Bake at 220–230°C (430–450°F), conventional, with the pan on the lowest shelf. Heat from below cooks the base before the surface.

Never wash the pan with soap

The black iron pan should be scraped and oiled, never washed with detergent. Over time it develops a natural non-stick patina that improves flavour.

Frequently asked questions

The boiled potato retains moisture thanks to its starches, keeping the focaccia soft for 24 hours. It was the method of old Bari's poor bakers to avoid losing unsold goods on the counter.
The original recipe uses only durum wheat semolina. The Consortium TSG specification prescribes it as the main ingredient. Some bakers add a small percentage of type-0 flour to make the dough easier to handle.
It's a rule written in the Consortium specification. By crushing the tomato by hand the juice spreads onto the raw dough, creating a natural marinade that soaks in during baking.
The traditional pan is round, made of black iron, with high sides. The iron holds and distributes heat evenly, creating the crisp base. It is never washed with soap: it's scraped and oiled. → Full iron pan guide
At least 2–3 hours for the dough to double, plus 30–45 minutes of second proofing in the pan. A slow overnight proof in the fridge produces a more digestible, flavourful focaccia.
Yes, there is a potato-free version with semolina hydrated to 80%. The result is crisper and denser, but it doesn't follow the TSG specification. For the typical softness of Bari bakeries, the potato is irreplaceable.
