I was transfixed by her auburn hair and all-American smile, which radiated from the cookbook propped up on our kitchen counter
^Did her hair actually radiate from the cookbook?
Betty Crocker was the obsession of my girlhood-- or so she was until I discovered, at the tender age of seventeen, that "Betty" was not a real woman
It was not until several years later
^I really do not understand this. You state that Betty Crocker was no longer an obsession of your childhood, when you were 17. Alright, that is fine.
But then you say, several years later, your interest in her came back. I am assuming that you are aged between 17-19. In that case, several years later is wrong given the context.
Quite frankly, I do not see the point in mentioning that you were no longer 'obsessed' with her. The time frame you have established is very weak in order to support your claims.
If you are trying to say that you admired her as a hero because you were a child, outgrowing this 'childish' interest at a rather shocking age of 17 just shows your lack of mature development.
**You do make a number of grammar mistakes in your essays. Quite a number of them actually.
The most obvious ones are in your concluding lines; you misuse pronouns.
Also, I was just wondering:
The three of us were from different backgrounds, distinct walks of life -- we were just different ingredients that happened to come together. Betty Crocker would have agreed
^Would Betty Crocker have agreed that you came from three different backgrounds, or that you were different ingredients that came together?
