This is a rematch between Iron Chef Morimoto and Chef Cantu.
In Battle Beet, Chef Cantu defeated IC Morimoto by one point.
Iron Chef Forgione served as the sous chef for his father during this match.  
After the active Iron Chefs are introduced by Alton Brown, the challenger chef is introduced.
The Iron Chef introduction sequence is sometimes skipped in the holiday shows and other specials.
In the first two seasons, the Chairman announced the challenger's Iron Chef opponent.
Starting with Season 3, the show returned to the format of its predecessor, where the challenger chef selects the Iron Chef they will battle.
In reality, the match-ups are determined well in advance in all three incarnations of the show, which is not to say that the challengers have no influence on the selection of their opponent.
An ingredient or group of ingredients (referred to as the "secret ingredient(s)") is revealed, and the cooking begins.
On occasion, the ingredients are actually a 'theme meal;' for example, eggs, bacon, potatoes, etc.
are revealed and thus the "secret ingredient" is breakfast.
Just as with the original "Iron Chef", the "secret" ingredient is not truly secret.
Both the competitor and the Iron Chef are given a list of three to five ingredients before the battle, of which one will be the secret ingredient.
Unlike "Iron Chef", where chefs had roughly 5 minutes to discuss their strategy before the battle begins, the revelation of the theme ingredient occurs 45 minutes before the start of the battle.
However, this segment is not shown on television, and it is a common assumption that the battle starts immediately after the secret ingredient is revealed.
This practice was described on an episode of "Unwrapped".
The Chairman announces the start of each battle with:  "So now America, with an open heart and an empty stomach, I say unto you in the words of my uncle: 'Allez cuisine!'
""Allez cuisine!""
(loosely translated as "Go cook!"
or "Start cooking!")
is the phrase that started battles in the original Japanese series (hence the reference to his uncle, Chairman Kaga).
On "Iron Chef America", both the challenger and the Iron Chef have 60 minutes to prepare a minimum of five dishes based on a theme ingredient.
Starting with Season 11 (2012–13), the first course is due to the judges 20 minutes after the start.
After that point, a "culinary curveball" is announced by the chairman.
It can be an ingredient, piece of equipment or plating device.
Each chef is required to integrate the item into their remaining dishes, and receives scoring from the judges based on their use.
After the first commercial break, Brown typically asks Kevin Brauch to introduce the judges.
Generally, Kevin pays homage to the program's origins by adding, "Konban Wa" (Japanese for "Good evening") to his introduction.
Unlike the original series, none of the judges participate in the running commentary, although Brown or Brauch visit with them roughly mid-battle for their comments on the ongoing action and the secret ingredient.
Over the course of the cooking hour, Brown may also provide further information on the theme ingredient, using visual aids as required.
The dishes are tasted by a panel of three judges, two of whom are professional food critics (a contrast to the original "Iron Chef", which typically had one professional food critic as a judge).
Like the original "Iron Chef", each chef can be awarded up to 20 points by each judge; consisting of 10 points for taste, 5 for plating (the appearance or presentation of the dishes), and 5 for originality.
The chef with the higher score is declared the winner.
If there is a tie, it remains as the final result, unlike "Iron Chef", where an overtime battle was immediately called with a new theme ingredient; however, if the overtime battle also resulted in a tie, that would be the final result.
(Also in contrast with the original, the final scores are subdivided by category, rather than by individual judge.)
Starting with Season 11 (2012–13), an additional 10 points per judge is also available: up to 5 points for the first dish presentation, and up to 5 points for the use of the "culinary curveball".
The scoring for the first dish is revealed shortly after the dishes are presented to and tasted by the judges, and the total score (including the "culinary curveball" points) is reserved for the judgment and revelation of the winner.
"Iron Chef America" is not affiliated with any culinary institution, unlike "Iron Chef", which was associated with Hattori Nutrition College.
Chefs also bring in their own sous-chefs.
Like "Iron Chef", each chef is allowed two sous-chefs.
In tag-team or two-on-one battles, both chefs on one side each bring one sous-chef.
On the original "Iron Chef", early episodes had two chefs without sous-chefs, while later episodes had two chefs and one sous-chef per side.
The sous-chefs employed by the Iron Chefs are as follows:  Batali – Anne Burrell and Mark Ladner  Cora – Lorilynn Bauer, David Schimmel, Ed Cotton, Richard Blais (other sous-chefs have been employed on occasion)  Flay – Flay employs a rotating staff of sous-chefs from his restaurants  Morimoto – Ariki Omae, Makoto Okuwa, and Jamison Blankenship (other sous-chefs have been employed on occasion)  Symon – Cory Barrett and Derek Clayton  Garces – Dave Conn, MacGregor Mann, Jessica Mogardo  Forgione - rotating staff of sous-chefs from Forgione's restaurants  Zakarian - Paul Cosentino, Eric Haugen, Alex Guarnaschelli (before her promotion to Iron Chef)  Guarnaschelli - Ashley Merriman and Wirt Cook All of the sous-chefs for both the Iron Chef and challenger are informally introduced at some point in the contest, unlike the original "Iron Chef."
Sous-chefs have occasionally entered into battle against Iron Chefs, including the Iron Chef under whom they worked.
The rules in "Iron Chef America" are thought to favor the Iron Chef less than the original program, however, some challengers have noted favoritism in the selection of theme ingredients.
On "Iron Chef" the Iron Chef's food was always tasted second, while on "Iron Chef America", the chef whose food is tasted first is determined by toss of coin before the show.
As the tasting and judgment take upwards of 45 minutes to complete (although it is edited down in post-production), the chef serving second is allowed to reheat his or her dishes, which was allowed on "Iron Chef".
Several of the secrets to how the show is taped were revealed in an episode of "Unwrapped" entitled "Food Network Unwrapped 2."
It was stated that the chefs find out what the secret ingredient is about 15 minutes before the battle begins because the opening sequence is recorded many times.
It is only the final taping of this sequence where the words ""Allez cuisine!""
are said and the battle begins.
Moreover, at the end of the one-hour battle, the chefs must still prepare 4 plates of each of their 5 dishes for the judges and the Chairman.
This is done during a 45-minute period after the battle ends and before tasting begins.
They consider this to be part of the competition, and it is timed, but it is not recorded or shown to the viewers.
The plates which the audience sees prepared during the one-hour battle are the plates used to obtain close-up footage of the dish for use in the final episode.
Usually, on taping days, two different battles will be taped, one beginning at about 10 a.m. and the second at about 4 p.m. A Food Network crew has about 90 minutes between each show to clean the set and prepare for the second show.
Chefs provide the producers with shopping lists for each of the possible secret ingredients.
Consequently, they can surmise what the secret ingredient will be just before it is officially revealed, based on which of their items were purchased. 
Tamara Murphy is the first female challenger to lose to the Iron Chef.
The three previous female competitors won their respective battles.<br>In this match Milliken and Feniger only had one sous-chef to adhere to the three-to-a-kitchen rule. 
Gordon Ramsay is the head chef.
The narrator is Jason Thompson.
Jean-Philippe Susilovic, a Belgian maître d' comes from Petrus, one of Ramsay's London restaurants and appeared in the first seven seasons and later returned for the 11th season.
Susilovic was also the maître d' for the first series of the original British version.
