     "Mom, can I bake some bread?"  We were 15; my best friend, Hanna, and I, determined to try our hands

at creating some beautiful bread.

     "It's not worth the trouble,"  my mother said."It takes lots of time and makes a big mess. Our bakery

bread

is delicious without all that effort."

     Begging was useless. Mom's"no" meant"No!"

     But several weeks later, opportunity knocked. My parents were going out for the evening. I immediately

invited Hanna to be my partner in bread-baking crime.

     We studied the recipe. That was easy. "Mix oil into flour then beat in four eggs, one at a time, with

remaining sugar and salt."

      We were not good at breaking eggs. I tried to learn from my mother.

      "Gradually add eight cups of flour. When dough (面团) holds together, squeeze it."

      We took turns working like that. "Is the dough 'holding together'?"  we asked each other.

      I remembered my neighbor's instructions: "If it's too sticky, add some flour; if too dry, add water."

      We added water. Then more flour. Then more water. By then, the mass of our dough had grown very

much. "Place dough on floured surface and squeeze till smooth,"  the recipe instructed.

     We took turns burying our hands in the damp dough, pinching, squeezing, and feeling it leak between

fingers. "Clean and oil bowl, and then return dough to bowl. Cover and let dough rise in a warm place for

one

hour."

     This was good news-we'd have a break. On the dirty kitchen chairs, we dreamed about our beautiful

bread. "See?" we would tell my mom. "Isn't it worth the work?" 

      Hanna and I couldn't help glancing at the rising process every few minutes. But nothing happened.

     "Maybe something will happen in the hot oven,"  I said.

     Unfortunately, when we removed the loaves from the oven, they were like hard stones.

     Mom was right; it takes time and effort. It sometimes makes a mess. But still it feels good, somehow, to

be part of that long, ongoing chain of bread bakers. Since that night, both Hanna and I have learned to do it

right.
