Purple sweet potato and raisin steamed cake

Overview

How to cook Purple sweet potato and raisin steamed cake at home

Steamed purple sweet potatoes.
Put the steamed purple sweet potato into a blender, add an egg, and beat the milk until smooth.
Add sugar and yeast to the well-beaten purple potato paste.
Add wheat flour and a little corn oil and mix well.
Blend into a dry paste.
Pour into the mold and add raisins and wait for fermentation. The time depends on the temperature at that time.
After fermentation, put cold water into the pot and steam for 35 minutes and simmer for 5 minutes! Don't simmer it for too long, otherwise it will be bad if water vapor drips in.
Pour out the mold and let cool.
Finished product, cut into pieces and eat!
