Dashi is the foundational soup stock of Japanese cuisine, providing the essential umami flavor base for miso soup, noodle broths, and simmered dishes. It is typically made by simmering or steeping kombu (kelp) and katsuobushi (dried, fermented, and smoked bonito flakes) in water. This simple yet profound broth is a cornerstone of Japanese home cooking and professional kitchens.
Dashi is an extremely low-calorie, virtually fat-free, and carbohydrate-free liquid. Its primary nutritional contribution is minerals from the seaweed, such as iodine, and small amounts of protein and B vitamins from the fish flakes. A standard serving contains roughly 5-10 calories.
