Recipe
Used glenn’s Mizu-yokan recipe for one layer, then a modified version of the sweets lady book recipe for Ama-no-gawa.
Sized to fit our smaller (12cm) nagashikan.
Mizuyokan:
- 250g koshian
- 250g water
- 50g sugar
- 3g kanten
Kingyokukan:
- 250g water
- 164g sugar
- Note from 2025-07-04: next time, try a little less sugar. Maybe 100g?
- 3g kanten
Making for those is as usual, ie:
- Add cold water and kanten together, then bring to a boil. Once boiling, let simmer for a min or two.
- Add sugar, boil, simmer for a min or two.
- Add koshian, boil, simmer for a min or two.
Method
Top layer (put in upside down)
- Spray the bottom of the nagashikan with water.
- Add gold flakes.
- Don’t worry much about getting it even; it will even out after the first pour.
- Make the kingyokukan.
- Pour in a very thin layer of kingyokukan, just enough to cover the gold flakes.
- They’ll rise to the surface, not really cover.
- Using a chopstick, spread the flakes around.
- Wait for that layer to cool (pretty much completely), then add the rest of the kingyokukan.
- Pour over the back of a spoon so you don’t have one sharp pouring point.
- No need to move the pouring all around though — pouring over the back of a spoon from one spot in the nagashikan, letting it flow to the rest, is good.
- (Do this if one portion of the thin layer is set, but the rest isn’t. You can pour into that set portion, and let the gentle flow cover the unset portion).
- Wait for that layer to cool, then make the mizuyokan layer and pour over the back of a spoon.
- IMPORTANT! DO NOT LET IT COOL TOO MUCH.
- MAKE SURE TO START THE MIZUYOKAN EARLY ENOUGH THAT IT’S READY TO POUR ONCE THE KINGYOKUKAN IS WOBBLY BUT NOT TOTALLY SET.
Cutting:
- Cut the nagashikan in half lengthwise (hot dog).
- Then cut 3cm slices.
