It is important to boil some pulses for the first 10 minutes to destroy any potential toxins that may be present, but after that reduce the heat to a gentle simmer so they soften without breaking up. Simmering times in the chart are approximate because older pulses take longer to cook. Aduki, black-eyed, borlotti, kidney and soya beans specifically require vigorous preboiling to destroy toxins but it does no harm to preboil all pulses.
Put the soaked pulses into a saucepan and cover with at least 4 times the volume of cold water. Add herbs, onion slices or diced carrots. Bring to the boil. Boil hard for 10 minutes and skim off any scum. Reduce to a simmer, cover and cook until tender (left). Top up with boiling water, if necessary. Drain, discard the flavorings and season. Toss with olive oil or vinaigrette if serving cold in salads.
