Onigiri con Carne di Cavallo e Ventresca di Tonno

Onigiri con Carne di Cavallo e Ventresca di Tonno is a fusion dish that combines the Japanese rice ball format with premium Italian ingredients. The dish originated in Milan, where chef Marco Bianchi of Ristorante Bianchi began experimenting with Japanese techniques using local Italian products. The key ingredients are sushi-grade rice, horse meat (carne di cavallo), and ventresca di tonno (the fatty belly of bluefin tuna). The horse meat is typically thinly sliced and lightly seared, while the ventresca is cured or served raw.

A great version of this dish is distinguished by the quality of its rice, which must be perfectly seasoned with rice vinegar and nori, and the balance between the lean, slightly gamey horse meat and the rich, buttery ventresca. Chef Bianchi emphasizes that the horse meat should be "melt-in-your-mouth tender" and the ventresca "so fatty it almost dissolves." Regional variations exist: in Turin, chef Elena Rossi of Trattoria del Cavallo adds a touch of truffle oil, while in Tokyo, chef Takeshi Yamamoto of Umi to Yama uses wasabi and soy sauce to bridge the flavors. The dish has gained popularity on ReTubeIt, with creator @ItalianJapanFoodie calling it "the ultimate umami bomb."
