Milky Purple Sweet Potato Cake

Overview

Homemade dream souvenir, milky purple sweet potato cake. Beautiful pink-purple color, cute pre-meal afternoon pastry, has recently become a popular product in my family. It was inspired by the popular souvenir purple sweet potato tart that my cousin brought to Japan not long ago. Purple sweet potato is a very common food. My mother often prepares steamed purple sweet potato as a staple food for breakfast. It left me with the impression that it has many benefits, but the taste is very dry and makes me choke. I ate the purple sweet potato tart brought from Japan this time. It has a delicate texture, sweet but not greasy, and it wiped away my bad impression of purple sweet potato. Homemade purple sweet potato cake can be refrigerated and eaten as a pastry, or it can be modified into purple sweet potato filling. It is a good choice for making bread and moon cake fillings. It will have different flavors when eaten hot or cold. The purple sweet potato puree is very soft when eaten hot, with a delicate and smooth texture. After being refrigerated, it becomes hard because of the butter, and it feels more like a mung bean cake. Purple sweet potato itself is pink-purple, but it will become darker after being heated and processed. The anthocyanins have a lively character and will change color under the influence of many factors. The secret to the beauty of this purple potato cake lies in lemon juice, because anthocyanins will turn pink when exposed to acid, and turn blue when exposed to alkali. After adding lemon juice, the color of the purple sweet potato puree will change and turn into a very beautiful pink-purple.
