Vegetable Preparation: Peel the carrot and cut it into bite-sized pieces. Cut off the stalk of shiitake mushrooms and optionally decorative cuts on the cap. Wash the komatsuna and cut it into quarters. Peel the yuzu, remove the white part, and shred it.
Prepare the Mochi: Place the mochi on a grill or toaster oven with a parchment sheet, and cook it for about 5 minutes or until it becomes puffy.
Make the Soup: In a saucepan, combine water, dashi powder, soy sauce, and salt. Add the carrots and heat over medium heat. Once it starts boiling, reduce the heat and simmer for 2-3 minutes.
Add the Vegetables: Add the komatsuna and shiitake mushrooms to the pot. Simmer for a few more minutes.
Serve: Place grilled mochi in a serving bowl and arrange the soup ingredients. Pour the flavorful broth over the mochi and ingredients, and finish by garnishing with shredded yuzu peel.
Notes
Storage: Store leftover soup in a glass jar or an airtight container in the fridge for up to 4 days. Individually wrap each leftover cooked mochi piece in plastic and refrigerate for up to 2 days.
Watch the mochi carefully: When grilling or toasting mochi, keep an eye on it so it doesn’t burn or puff up too much.
Adjust the Soup Seasoning: If the soup tastes too salty, dilute it with a small amount of water. If it’s too mild, add a little soy sauce or salt to tweak the flavor.
Make the broth ahead: You can prepare the clear soup ahead of time. Simply reheat it gently before serving and add the mochi at the end.
