Proof the yeast in a bit of the water and then add the rest of the water and the oil and blend well. Knead the dough for a good ten minutes. It should be velvety and elastic
Let the dough rest for 1-2 hours until it has doubled.
Tip the dough out onto the (unfloured) counter and divide into two or three pieces depending on how big you want the focacce. Oil your containers well – round, square, or rectangular, shallow baking trays that are about 1.5-2 inches (5 cim) deep. Roll out our dough to fit the containers and then place them in the containers and cover with damp towels for 30 minutes.
Dimple the dough and let rise for 2 hours. After 90 minutes, pre heat the oven to 200 degrees C.
Top with olive oil and salt or fresh sage or tomatoes or whatever you want. Only 2-3 tablespoons of oil per focacce.
Place the baking trays with the bread in them on to a hot stone or hot baking tray (you have heated in the oven) and bake for 20-25 minutes. When they are done, immediately invert them onto cooling racks so they don’t get mushy. Eat them at room temperature the same day you bake. They don’t keep.
