Takoyaki variation with tofu and nagaimo 長芋豆腐たこ焼き

This is a takoyaki たこ焼き ("tako grill") variation made without "tako" (octopus). This recipe is from "The real Japanese Izakaya Cookbook". We made takoyaki (octopus inclusive) using an electric ebelskiver maker before. An ebelskiver maker is the closest we could come to a traditional takoyaki grill.  This recipe deviates significantly from the traditional approach because it uses grated nagaimo 長芋 and tofu 豆腐 instead of flour. Instead of tako is uses hijiki ひじき sea weed and edamame 枝豆 . Continuing on the innovative theme, instead of the usual "Takoyaki sauce", this recipe used "Gin-an" 銀餡 which is a milder and "more sophisticated" sauce.

The surface was nicely brown and crunchy.

The inside was soft and hot showing hijiki (black stringy below) and edamame (green).

Ingredients: (I tried to halve the amount of the original recipe. I ended up making some changes inadvertently, since I just did not want to use "half egg" and I did not want to leave a small portion of nagaimo).

The original recipe is as follows;

1 firm silken tofu 12oz (350g)
Handful dried Hijiki seaweed
8 oz (225g) unshelled edamame pods (then, cooked and shelled)
1 egg
4oz (125g) yamaimo
1/2 tbs sugar
1/2 tsp salt

The amount below are what I think I used. It made 6 balls using the Ebelskiver cooker (the balls were larger than regular takoyaki) as below.

1 small package of silken tofu, about 125gram, wrapped in paper towel with a weight (I used wooden cutting board) to drain for 1 hour.
Nagaimo, skin removed and grated, about 120g (I used up what I had left)
1 egg
Hijiki seaweed, hydrated, arbitrary amount
Edamame, frozen, cooked and shelled, arbitrary amount
Pinch of salt and sugar
"Katakuri-ko" potato Starch (because, proportionally I used more nagaimo and egg than the original recipe which made the batter runnier, I added potato starch to adjust the consistency of the batter).

For the dipping sauce; (this is the original, again, I halved the recipe when I made it)
2 tbs potato starch
2 cup (500ml) dashi
1 tbs soy sauce
1/2 sugar
1/2 tbs mirin
1/4 tsp salt

Directions:
Using a small food processor, I mixed the tofu, grated nagaimo, egg, salt and sugar until the batter was smooth. I then added the potato starch in small increments to adjust the consistency (it was the consistency of a bit runny pancake batter).
I added the hijiki, edamame and mixed (#1)
I preheated my electric ebelskiver to medium high (#2)
I poured the batter filling 6 wells (#3)
After the bottom got set and browned (it took a few minutes, I was too inpatient and started flipping too early)
After several flipping, the surface started getting evenly brown (#4)
I kept flipping until the surface is all cooked and browned about 5-6 minutes (#5 and 6).

This version of takoyaki was good and the dipping sauce went well with it but this is not really takoyaki (I am sure people from Osaka would agree). It is a dish in-and-of its own just resembling the shape of takoyaki. Making  this requires some steps and effort and I would rather make  regular takoyaki which is much easier to make.
