My mother, and actually her mother before that, made modifications to the Nestle Tollhouse chocolate chip cookie recipe. Specifically, replacing butter with shortening and using just a bit of extra flour, while whipping the eggs a bit more in mixing. I watched an episode of Alton Brown's Good Eats where he made that exact set of modifications to get puffy/cakey chocolate chip cookies, some 20 years after Grandma started baking them that way. It's always amusing to see your old school process be supported by proper food science.
