Step 3: Add some flour and knead it
Once it gets too tough to stir, flip it onto a clean floured surface. Now, knead away, adding flour as you do so.
Knead the dough for 8 or 9 minutes. As my Mother says, it should be the texture of your earlobe when it's done kneading.
When you finish this part put it back in the bowl and cover it with a slightly damp towel.
