* EurekaMoment: Whenever Yoichi is unsure about what to do to solve his culinary problems at hand, expect to him to encounter something seemingly unrelated that will inspire and lead him to a needed solution soon afterwards.

* PosthumousCharacter: Yoichi's father overlaps this trope with DisappearedDad, as he's been dead for years before the series begin, though he still manages to remain relevant due to the combination of the Hinode Eatery under his management back when he was alive (before his death caused the ownership status to be passed on to his wife), Yoichi having gained some cooking through him, and several of his friends/associates who received help from him in the past needing help in the present time and triggering Yoichi's drive to help AFriendInNeed.

* AFriendInNeed: Quite a few story-lines culminate in CookingDuel because Yoichi finds out about some former business associates of his father's who need help maintaining a food-related business. The few story-lines that don't result in him getting involved in some CookingDuel are mostly the ones where someone Yoichi knows has health-related issues and needs him to make delectable dishes to help them get better.

* HereWeGoAgain: One StoryArc later in the series starts with a young woman Yoichi meets at a campsite getting angry at her boyfriend because he promised to bring food in advance but forgot to do so until well after the fact. Yoichi spends the whole StoryArc helping them out by getting food sources and cooks for them[[note]] (this is one of the few story-lines with no CookingDuel taking place throughout)[[/note]], only for it to end with [[ShaggyDogStory her boyfriend scarfing down nearly all of the food Yoichi manages to scrounge up and cook for them]] and the woman chewing her boyfriend out for his lack of consideration for anyone else.

* KidHero: Yoichi is the main protagonist of this series. While his exact age is not clearly stated, he's always drawn as a minor throughout the run of the series.

* SlidingScaleOfIdealismVersusCynicism: Since almost all conflicts in this series are resolved with CookingDuel, quite a few of which end with DefeatMeansFriendship or BreakTheHaughty at least, and whatever promise the losing side made before said CookingDuel [[IGaveMyWord will keep it afterwards, whether by themselves or with additional prodding]], this series is firmly rooted at the side of idealism.

* SlidingScaleOfIdealismVersusCynicism: Since almost all conflicts in this series are solved with CookingDuel, quite a few of which end with DefeatMeansFriendship or BreakTheHaughty at least, this series is firmly rooted at the side of idealism.

** Many a challenger who doesn't take Yoichi seriously as a culinary rival bases their attitude due to Yoichi being unmistakably a minor. Naturally, Yoichi proves them wrong when the CookingDuel takes place. This happens more so early on in the series, when Yoichi is still unknown in the culinary circles. Once Yoichi's culinary reputation starts building up, this trope occurs much less often.

* BrickJoke: Early in a steak CookingDuel contest hosted in a beef conference that Yoichi signs up for, in which the material of choice is imported lean beef with no fat and the sponsor announces that the winner of said contest will receive a one-year supply of beef, he asks for a tip about how to soften foodstuff from a market owner who sells hand-harvested black soybean that he personally softens before selling. The market owner confides the secret to Yoichi after learning that Yoichi intends to apply such a method on imported lean beef and his son nudges him into revealing the method to Yoichi, and Yoichi runs home to put it to the test, though not before the market owner's son calls out after Yoichi saying that Yoichi should treat them for steak should he win the contest. After the steak CookingDuel concludes with Yoichi as the winner, the market owner's son shows up behind Yoichi for steak.

* PlayerElimination: The CookingDuel being hosted by the Ajio Company [[VotedOffTheIsland eliminates the contestant that a panel of judges being randomly selected from the general populace determines to be the worst performer, one at a time, in a similar fashion to musical chairs]], until only one contestant (or, in the case of both remaining contestants being judged as equally good, two) would remain as champion(s).

* SupremeChef: Yoichi, definitely. The same applies to any CookingDuel contestant who can rival his culinary skills.

* StoryArc: This series follows a linear progression pace.

* HereWeGoAgain: One StoryArc later in the series starts with a young woman Yoichi meets at a campsite getting angry at her boyfriend because he promised to bring food in advance but forgot to do so until well after the fact. Yoichi spends the whole StoryArc helping them out by getting food sources and cooks for them[[note]] (this is one of the few story-lines with no CookingDuel taking place throughout)[[/note]], only for it to end with [[ShaggyDogStory her boyfriend scarfing down nearly all of the food Yoichi manages to scrounge up and cook for them]] and the woman berating him for his lack of consideration for anyone else.
