“The apple was the first fruit according to Genesis, but it was no Cox’s Orange Pippin. God gave the crab apple and left the rest to man.”
There is no question in my mind that the finest cooking that I have experienced has been from a master craftsman whose originality comes from a slight tweak of a tradition or a re-discovery of a lost dish. Even then the originality is less important than the execution. I also harbour little doubt that the worst meals I have been subjected to – worse than sloppy craft – are those where the cook, professional or otherwise, takes it into his or her head to try something new.
Please rather just improve. Only in incremental improvement will you find excellence.
