We are upgrading the EDC, the time is right to do that as we have not really ever tested all that is in there, it was compiled before my time from recipes that had been tested by customers and consultants. In the books defence, I think it covers the basics extremely well with a wide range of dishes that demonstrate the many functions of the TM.
I have also thought so - just being a home cook, cooking basic meals for family, I have never had issues with poor ol' EDC - It has served me well.
