Madeira Sweet Potato Flatbread (Bolo do Caco)

Bolo do Caco is the iconic flatbread of Madeira island. Named after the 'caco', a hot basalt stone slab it was originally baked on. Uniquely, cooked sweet potato is kneaded into the dough, keeping the crumb incredibly soft and slightly sweet for days. Though we use a skillet today, contact heat remains key for the signature thin crust.

Instructions

1

Mix sugar and yeast in lukewarm water. Let stand 10 mins until foamy.

Tip: Foam indicates yeast is alive and fermenting.
2

Mix flour and salt. Add cooled sweet potato mash, yeast water, and olive oil. Knead until smooth but slightly tacky.

Tip: Sweet potato starch holds moisture, keeping bread hydrated.
3

Cover and proof in a warm place for 45-60 mins until doubled.

Tip: Consistent temp prevents drafts.

Turn onto floured board, divide into 4, shape into flat discs (1 inch thick). Rest 15 mins.

Heat a heavy skillet (dry!). Cook muffins on medium heat 5-6 mins per side until dark spots appear and cooked through.

Tip: Dry heat mimics the traditional stone baking.
