What's the secret recipe

It was loose and soft. When the chopsticks picked it up, a part of it would be dented. It was very fluffy. When he looked closer, he found that the surface of the mantou was very smooth and glossy.

Jiang Nuan opened her mouth and bit off half of it in one bite. She swallowed it and chewed. The first thing she felt was the faint fragrance of the Lotus leaves, followed by the soft texture. After chewing carefully, there was a hint of sweetness and a natural hint of sourness.

"Grandma's secret recipe?" Jiang Nuan was stunned.

It was just a little, and if one didn't pay attention, they wouldn't have noticed it. It was the familiar sour taste that awakened Jiang Nuan's memory.
