The Japanese movie Sweet Bean (あん) shows the process of making red bean paste in one of the scenes. The cook uses a clear gelatinous substance which presumably is the sweetener for this paste. What is it exactly?

Best Answer

The ingredient is Mizuame (水飴), a Japanese sweetener. It adds sweetness and gives a luster.

When they need large amount, professional cooks usually scoops it with their bare hands, as she does in the movie. I'm not sure of the reason, but Mizuame is very sticky and it is troublesome to handle with tools.

And this behavior explains that she has long experiences in making read bean paste.
