Mix flour, bicarbonate and salt evenly.
Bicarbonate should be dispersed without concentrated pockets.
Torta al testo is Umbria’s simple griddle bread, named for the hot flat “testo” on which it cooks. Flour, water, salt and bicarbonate make a soft dough that is rolled into a thick round, pricked and cooked slowly on both sides until dry, lightly browned and ready to split or fill.

Umbriatourism describes the testo or panaro as the traditional flat heated surface used for the bread and gives a straightforward formula of flour, bicarbonate, salt and warm water.
The dough is kneaded until smooth and elastic, then rolled to roughly 1 cm rather than the thinness of piadina.
Fork-pricking controls large bubbles so the round stays evenly in contact with the griddle.
Low to medium heat is essential because the flatbread is thick enough to burn outside before the centre cooks if the plate is too hot.
Mix flour, bicarbonate and salt evenly.
Bicarbonate should be dispersed without concentrated pockets.
Work in enough warm water to form a soft cohesive dough.
The dough should be soft and pliable but not sticky enough to smear.
Knead about 10 minutes until smooth, then cover and rest 15 minutes.
The surface should be even and the dough should relax under the hand.
Heat a cast-iron griddle over low to medium heat for several minutes.
The surface should be evenly hot without smoking.
Roll the rested dough into one large round about 1 cm thick, or divide for two easier rounds.
Thickness should be uniform from centre to edge.
Pierce the surface all over with a fork just before cooking.
There should be many small vents and no large untouched area.
Transfer to the hot griddle and cook around 8–10 minutes, rotating occasionally.
The underside should show dry toasted spots without black patches.
Flip and cook the second side another 8–10 minutes, adjusting heat downward if needed.
The centre should feel firm and cooked rather than doughy when pressed.
Cool 3–5 minutes, cut into wedges and serve warm, plain or split for fillings.
The crumb should be tender enough to split while the surfaces remain lightly toasted.
Traditional serving can include greens and sausage, prosciutto, cheese or vegetables; the base recipe remains deliberately plain.
Umbriatourism notes related regional names including crescia around Gubbio and pizza sotto il fuoco around Terni.
Some modern Umbrian formulas include a little olive oil and sparkling water. This version follows the simpler official flour-water-salt-bicarbonate formula.
Estimate is for plain bread without fillings.
Contains gluten.
Take care when transferring the thick round to a hot cast-iron surface.
Cool filled leftovers promptly if using meat, cheese or cooked vegetables.
Traditionally it is the flat heated stone or later clay/stone surface used to cook this Umbrian bread.
The cited traditional recipe rolls it to about 1 cm.
A heavy cast-iron griddle or skillet is the most practical home substitute because it stores and distributes heat well.
