Tradition and Trend

My mother makes the best pot roast, and I wanted to try to replicate it for my children. So, I called my mom and asked her for the recipe. She started to explain, “First you take the roast, and you cut it in half and put it in the pan...” I interrupted, “But, wait, why do you cut it in half?” My mom told me that she got the recipe from my grandmother, and I should ask her. So, I called my grandmother.
