Everyday kitchen measurements

For 2 servings. Use a small 180 ml paper cup, a level eating spoon (about 15 ml) and a small teaspoon (about 5 ml).

How to fill the cup and spoons

Use the same cup and spoons throughout. Their sizes vary, so these amounts are approximate. Spoon flour in loosely and level the top without pressing. Measure vegetables after chopping, without packing them down. The amounts in g/ml are the original reference quantities. For part of a pack, use the specified pack weight and divide the contents evenly.

Step-by-step cooking

  1. Step 1

    Prepare the vegetables before the fish: peel radish and cut 3 mm quarter-moons, mince garlic and slice spring onions. On a separate clean board cut thawed cod into 4 cm chunks, remove any pin bones and pat dry. Wash hands and utensils after handling raw fish; do not rinse it under a splashing tap.

  2. Step 2

    Put water and the optional kombu in a pot. Warm over medium heat for 8 minutes, then remove the kombu as the water reaches a gentle simmer. Do not boil the kombu hard. Without kombu, simply bring the water to a simmer.

  3. Step 3

    Add radish, garlic and soy sauce. Simmer over medium-low heat for 6–8 minutes until the radish is almost tender and a knife enters it easily. If your slices are thicker, finish softening them now rather than overcooking the fish later.

  4. Step 4

    Slide cod into the gently bubbling broth. Cook 6–8 minutes, depending on thickness, until the thickest center reaches 63°C and the flesh is opaque and flakes easily. Do not stir vigorously or boil hard; use a ladle to skim foam without breaking the fish. Continue cooking if the center is still below 63°C.

  5. Step 5

    Add spring onions and simmer 1 minute. Taste the broth, then add optional salt a little at a time. If too strong, add 30–about ¼ paper cup + 1 small teaspoon (50 ml) hot water. Ladle gently into bowls and serve hot, keeping the fish pieces intact.
