McDonald's is introducing a new Special Grade Garlic Sauce in the United States, available exclusively through its app starting July 9th. The limited-edition condiment is inspired by the Black Garlic Sauce from McDonald's in Japan and is launched in collaboration with the anime "Jujutsu Kaisen." The sauce features garlic and soy sauce flavors with a hint of tangy sweetness and comes in containers adorned with characters from the anime series. In addition to the sauce, eligible subscribers can get a free 30-day trial of the anime streaming service Crunchyroll with their in-app order.
