Kombu

Dried kelp, and the richest natural source of glutamate there is — the savoury half of Japanese dashi, and a quiet seasoning wherever it's simmered.

What to do with it

Kinds

Ma-kombu
Broad and sweet; a clear, elegant dashi.
Rishiri
Clean and salty; the Kyoto choice for clear soups.
Rausu
Rich and quick to give, but clouds the stock.
Hidaka
Softer; for simmering and eating.

If you can't find it

Japanese and Korean grocers, in dried sheets.

  1. A small pinch
    You lose the sea — MSG gives the savour, not the taste of kelp.
Honestly

Nothing gives the same base of savour and sea; MSG gets you halfway.

Knowing it

Where to buy
Japanese grocers. Thick, dark sheets; the white powder on them is flavour, not mould — wipe, don't wash.
Worth knowing
For dashi, soak it cold overnight, or hold it at about 60°C for an hour, and lift it out before the water boils. For kombu-jime, sandwich raw white fish between damp sheets for a few hours: it seasons and firms the flesh.
