1 piece of kelp (roughly 4" x 4" size) or ½ teaspoon kelp powder
4 cups water
¼ cup miso (adjust to taste)
½ cup baby spinach (loosely packed)
⅓ cup corn (frozen or fresh)
A pinch of salt
Instructions
Cut a piece of kelp into roughly 4" x 4" piece (if it's shriveled up, just roughly measure the length) and let it soak in the water overnight. Take out the piece of kelp when it is ready. The leftover soaking water is the dashi.
Place the baby spinach in a bowl and add in a pinch of salt and massage until it is wilted. Let it sit for a few minutes.
Pour the dashi into a sauce pan. *If you are using kelp powder to make instant dashi, skip the soaking part and add in water to the sauce pan, then the kelp powder and mix well.
Wring out the baby spinach well. Add the baby spinach and corn into the sauce pan.
Heat it up on the lowest flame to about 110℉. Check the temperature constantly so it doesn't overheat, and stir constantly to ensure there are no hot spots.
Once the temperature reaches 110℉, turn the heat off. In a small sieve, put the miso in and melt it in the soup using a spoon or whisk by rubbing it against the sieve.
Check the temperature once the miso is completely melted. If the temperature lowered, reheat on the lowest flame until it reaches 110℉. Be sure to stir constantly to avoid hot spots.
Transfer into bowls and serve immediately before it cools off.
Notes
Miso's saltiness varies depending on the brand and type of miso you are using. Adjust the amount of miso you use according to taste.
You can cut the removed kelp into small pieces, freeze it, and add it into your smoothies for added iodine.
How to make kelp powder: 1. Cut the kelp into smaller pieces and blend in the blender until powdered. 2. Transfer into a coffee grinder and finely grind until it becomes a fine powder. 3. Run through a fine mesh sieve to get rid of any larger kelp pieces.
