Scallion Cakes - Cou you bing

Cou you bing

3 cups all-purpose flour
1 cup water
10 to 15 scallions (depending on their size)
1 1/2 teaspoons sesame oil, approximately 1 teaspoon salt 1 1/2 tablespoons lard, at room temperature, or peanut oil (if you fear cholesterol)
(half the scallions)1 teaspoon salt
1 1/2 tablespoons lard
(remaining scallions) 3 tablespoons peanut oil, approximately

PREPARATION

Mix the flour and the water together very well; you should get a very stiff dough. Set it aside for at least 30 minutes.
Trim the scallions, then chop them, both white part and green, into very fine pieces, about the size of a match head.
Since the dough for the scallion cakes has to be rolled out, you will need the same kind of a large flat surface that you use for making any other kind of pastry, a large wooden board or tabletop. Prepare the surface on which you are going to roll out the scallion cakes by sprinkling it with the sesame oil. (This serves the same purpose as flour in keeping the dough from sticking. )
Knead the dough for about a minute until it is easy to work with, then separate it into two balls. Take one ball and roll it out into a rectangle about 8 by 10 inches. (If you are using a rolling pin, make sure to rub it with some sesame oil so that the dough doesn't stick to it. You can also use your hands instead of a rolling pin to press the dough out.)
Sprinkle 1 teaspoonful of the salt over the rectangle of dough. Press the salt into the dough with your fingers.
Spread the lard generously over the dough.
(Although you can use a knife to spread the lard, it is easier, though less aesthetic, to do it with your fingers.) Sprinkle half of the chopped scallions over the rolled-out dough, then roll the dough up like a jelly roll. Pinch the ends of the roll together so the scallions don't fall out, then divide the roll into three sections, twisting the ends of each segment to keep the filling from falling out. Each piece should be roughly the size of a tennis ball.
Using more salt, lard, and the remaining scallions, do the same thing to the other half of the dough.
Just before you are ready to begin cooking the scallion cakes, take one of the balls and gently flatten it out into a circle about 8 inches in diameter. This is the trickiest part of making the scallion cakes, for it is very hard to keep them from breaking open slightly while you are flattening them and letting the scallions escape. (Even Mrs. Chiang has trouble keeping the scallion cakes from bursting while she is pressing them out. ) Luckily, it doesn't make too much difference if the cakes split slightly at this point. Make sure that the surface on which you are working is still well oiled.
While the first cake is cooking, you can press out the next. (You can't really flatten them all out in advance, because it is not a good idea to handle them very much before you cook them.)
COOKINGHeat a regular flat frying pan over a moderate flame and fill it with 1/4 inch of oil.
When the oil is quite hot and has just begun to smoke, put in the first scallion cake. Let the cake fry for about 3 minutes on each side, until it has turned golden brown and become quite crisp.
Remove the fried cake from the hot oil and let it drain on paper towels.
Fry all the other scallion cakes in the same way.
Serve each scallion cake cut into 8 wedge- shaped pieces. (Since the cake is so crisp, it may be easier to cut with a cleaver than with a regular knife.) Note : Although there is plenty of salt inside the scallion cakes, they are especially delicious if you salt their after they have been fried .
