Ingredients (serves 2-3)

• 1 pound / 450 grams fresh fava beans
• 1/2 pound / 8 ounces / 225 grams red spring onion
• 2 tablespoons /  30 ml extra-virgin olive oil
• 1 1/2 cups / 355 ml water, or as needed
• 3/4 tablespoon miso (see note below)
• finely chopped chives for garnish, optional

Instructions

Note: the miso I use is aged 3+ years, like red miso, but it is made using green lentils rather than soybeans. It has a relatively mellow flavor. I suggest using yellow miso first. Depending on your preference, you may then mix it with some red miso for a stronger flavor (or with white miso for a lighter one).

Shell the fava beans and blanch them for 30 seconds, then drain them and plunge them into a bowl of ice-cold water to stop the cooking.

Slit the skin with your thumbnail then pinch or twist to slip the bright green core out of its coat and into a small bowl. (You don’t need to peel tiny fava beans, whose skin is quite thin.) Set aside.

Chop the spring onion.

Heat up the olive oil in a saucepan, then add the onion and stir well to coat. Cook on low heat until the onion is soft, 6 minutes or so, stirring often.

Add the fava beans to the saucepan and stir well. Pour the water into the saucepan: the vegetables should be submerged, but visible just below the surface. (Add more water if necessary.) Cover the saucepan and bring the soup to a boil.

Cook the soup on low heat until the fava beans are soft, 25-30 minutes or as needed. Stir every now and then with a wooden spoon and mash some of the fava beans against the side of the saucepan.

Put the miso in a small cup. When the soup is almost ready, spoon some of the liquid into the cup and stir to blend. Pour the diluted miso into the soup and stir well.

Remove the soup from the heat. Serve hot, with some chives sprinkled on top, if desired.
