Daikon and Potato Puree with Kombu Dashi

Name: Daikon and Potato Puree with Kombu Dashi
Cuisine: Japanese
Ingredients: 50g daikon radish, peeled and sliced; 50g potato, peeled and diced; 1/2 cup (120ml) kombu dashi (cold-brew: soak 5cm kombu in water for 30 min, remove kelp); Extra water as needed

Jump to Recipe

Daikon (Japanese white radish) is one of the most versatile vegetables in Japanese cuisine - pickled, simmered, grated, or eaten raw. For babies, it is introduced cooked and pureed, as cooking transforms daikon's mild pungency into a sweet, mellow flavor. Japanese mothers often pair daikon with potato because the combination creates a naturally thick, smooth puree without any added thickeners. The kombu dashi base - made simply by soaking dried kelp in cold water - provides a mineral-rich, allergen-free umami that is considered the purest form of Japanese flavoring for babies.

Mild and soothing daikon radish paired with creamy potato, simmered in kombu dashi. A gentle introduction to the delicate umami flavors at the heart of Japanese cooking.

Ingredient Substitutions

Can't find Japanese ingredients? Here are alternatives available at most supermarkets.

Daikon → turnip or parsnip (similar mild flavor when cooked)
Kombu dashi → plain water (flavor will be milder but still nutritious)
Potato → sweet potato for a sweeter variation

Instructions

01Prepare kombu dashi if not already done: soak a piece of kombu in cold water for at least 30 minutes, then remove the kelp.
02Place daikon and potato in a small pot with the kombu dashi.
03Bring to a gentle boil, then reduce heat and simmer until both vegetables are completely tender, about 15-20 minutes.
04Reserve the cooking liquid.
05Transfer vegetables to a blender and blend, adding cooking liquid to achieve desired consistency.
06For 5-month-olds, blend very smooth. For 6-month-olds, a slightly thicker texture is fine.
07Strain through a sieve if needed. Cool to body temperature before serving.

Tips from a Dietitian Mom

Cold-brew kombu dashi is the easiest method - no cooking required. Just soak and use.
Potato provides a natural creamy thickener - no need to add oil or dairy.
Daikon has a very subtle flavor when cooked; if baby resists, try mixing with a little kabocha or sweet potato puree.
The kombu in dashi contains natural iodine - important for thyroid function in growing babies.

Storage & Freezing

Refrigerate for up to 24 hours. Freeze in ice cube trays for up to 2 weeks. Note: potato-based purees can become slightly grainy when frozen - blend briefly after thawing to restore smoothness.
