smooth and elastic. resist the temptation to add too much flour; the dough may feel sticky but it will become less so as you knead it. it should be soft and slightly tacky, not stiff or dry.
3. form the dough into a smooth ball. pour about one teaspoon of olive oil into a large bowl. place the dough in the bowl and twirl it around to coat it with oil on all sides. place the bowl inside a plastic bag (a clean trash bag or plastic grocery bag will do) and loosely tuck the open ends underneath the bowl. puff up the top of the bag to form a tent.
