Instructions
Preheat oven to 350 degrees F (190 C) and have ready an ungreased cookie sheet.
Beat the butter, both types sugars, and vanilla together in a medium bowl, using an electric mixer. When creamy, beat in the egg. When egg is well blended, add salt and baking soda and beat well, scraping sides of bowl once or twice and making sure baking soda is well distributed throughout batter. Add cornstarch and stir until blended. Add flour and stir until it is almost blended in. Add the chocolate chips and stir until all flour disappears.
Drop dough by rounded teaspoonfuls onto the ungreased cookie sheets. Bake one sheet at a time on center rack for 10 minutes or until edges are golden brown. The cookies should get very brown around the edges, but do take care not to burn the bottoms.
