This is a Japanese-style spicy sausage sauce with garlic and chili aromas, along with dried horse mackerel flakes. The salty "homemade chili oil" fried in chili oil enhances the spiciness, and when combined with homemade garlic oil and garlic slices, the flavor becomes even richer. You can fully enjoy the "umami" with Japanese ingredients, such as kombucha soaked in sauce and bonito flakes as toppings.
