Most of the posts for HK2 have dealt with the seemingly poor quality of the candidates. Part of the problem is they were selected by the producers based on their resume and a videotape each candidate made. This is what I would like to see.
1. Regional Cookoffs - The country would be divided into regions with a famous chef from each region (or Ramsay) as the judge. Candidates from each region would have thirty minutes to prepare a dish. Each dish would be judged on taste, appearance and technique.
2. Taste Tests - You can't be on the show unless you can identify by taste certain basic meats, vegetables and spices.
These two tests are consistent with the tests Ramsay uses in "Kitchen Nightmares." In fact, I think both tests should be used to eliminate candidates in the early rounds vs. the line.
