*Kombu is an edible kelp – a mineral-rich seaweed and adds a savoury flavour to dishes. You’ll find it in the supermarket’s Asian section, or source it on line.
Don’t salt the broth during cooking, as this will make dishes in which you use the broth too salty – it’s best to add salt as you use the broth.
The broth will keep well in the fridge for several days and 3 months in the freezer.
Avoid storing, freezing and defrosting food in plastic containers – they leach endocrine disrupting chemicals into the food.
