Dashi Stock

Dashi is a Japanese fish broth that is easy to make when you need a fast and nutritious stock. Dashi stock is made out of katsubushi – dried bonito fish flakes – and kombu – dried kelp. Research shows regular consumption of dashi broth assists in maintaining healthy  blood pressure and reducing oxidative stress. It is rich in amino acids, iron, vitamin B12, and iodine which helps to support thyroid function.

You don’t need much to make dashi stock, just katsubushi flakes, kombu, and water. Katsubushi and kombu are available at Asian grocers. Kombu  is a fantastic food to include in the diet as there’s not that many sources of iodine in standard Western diets.


1 litre of water
10g katsubushi
