As you know, I've been following this thread for some time now and have tried some of your pizza recipes for the Mack's clone. I even served one to my "special Mom". I'll be trying your latest recipe again soon. I really liked the earlier attempts and can't wait to see your further improvements. But, I'm sure my pizza will be different from yours and different from Mack's, and Macks may vary by day, week, season, etc.
I've been brewing beer for over 18 years and, without bragging, am considered very accomplished by more that a few professional brewers with international reputations. Beer, like pizza, can not be cloned completely. The same recipe made by two different brewers and brew systems will differ in the end product. Beers that are known for their consistency can only be accomplished by blending different batches, practical only on the very large scale.
What I'm trying to say here is that while you may not feel that you have cloned the Macks pizza to your specifications, does not mean that you have not produced a spectacularly close representation of a Macks style. Your sensory evaluation of pizzas is far more sophisticated than the average connoisseur and your ability to discern fine differences in taste and texture lead you to be less than fully satisfied with your efforts. I know, I used to try to clone beers, everybody said they were on, but, I knew where I differed or failed to nail a certain characteristic and was rarely happy. Eventually I stopped even trying to clone, what I do now is taste a beer and make one similar in style, color, basic flavor, carbonation, etc., but, I put my stamp on it and vary some aspect of the product to the way I think things should be. I make a better beer, at least to me.
Norma, if you are burnt out on the cloning effort then... stop cloning. Take all you have learned, all you have achieved and make YOUR Macks pizza. Your interpretation of a Macks, a pizza one that you are passionate about. This is what I eventually did with beer and the freedom was awesome. I had learned so much cloning, brewing to style that I was able then to break the rules with abandon and know the final product would be awesome. You have learned the rules, now break every last one of them and use them as techniques to achieve a Norma's that everybody else will want to clone.
