A traditional 東北 region sweet, relying on the rising power of soda and vinegar. Has lots of brown sugar, so it's quite suitable for autumn.
45 gr egg
110 gr brown sugar
➡️ Whisk together, then add, in that order:
50 gr honey (I used pine and it was fine)
90 gr water (seems like a lot, but it's fine)
3 gr baking soda (Natron) in 3 gr water
6 gr oil (I used walnut, which was fine, but didn't really make a difference)
1 Tbsp 醤油
2 tbsp vinegar (I used black vinegar, but I don't think you can taste it in the finished sweet. Cider vinegar might be very autumnal!).
Finally, sift in:
Fold, then steam in baking sheet lined 流し器 (I steamed it in the Creuset rather the 蒸籠 and it turned out great):
10' with lid ajar full strength
10' with lid, cloth wrapped, closed, medium strength
Then sprinkle with sesame seeds
Steam for another 20' with the lid closed, medium strength.
