Stick a bamboo skewer through the cake, and if the skewer comes out clean, the chiffon cake is done.

This is the can of adzuki beans I used.
-
29
The beans have not be mashed, and there isn't much paste.
-
30
If you are using this type of adzuki beans, use 100 g.
-
31
This is a picture of another type of cooked adzuki beans.
-
32
The texture is mushy and sticky, and more like paste.
-
33
If you're using this type, use 80 g.
-
34
This picture is a chiffon cake using the canned adzuki beans paste mentioned at Step 14.
-
35
The chiffon cake is still fine and fluffy, but it hasn't retained the shape of adzuki beans.
-
36
Make this chiffon cake using the sweet adzuki beans you like.
-
37
This one is about in the middle of Step 13 and 14.
-
38
Use 90 g for this type.
-
39
Decide the amount to use depending on how the adzuki sweet beans looks like, or use the one mentioned in the recipe.
-
40
Adding the adzuki beans and chestnuts might let the chiffon cake deflate depending on the weight of the adzuki beans and chestnuts, so after cutting, wrap the cake with plastic wrap and sore the cakes in a tupperware to store.

FYI: For 18 cm in diameter mold: Change 3 large sized egg yolks to 4 large sized egg yolk; 60 ml of milk to 80 ml; then 60 g of cake flour to 65 g.
