Since things had come to this, Lu Xinyi endured and closed her eyes, focusing on the taste. As the liquid swished on the other side of her mouth, she was able to taste some vegetables like broccoli, brussels sprouts, cabbage, kale, radishes, and arugula. However, there was this layer of sour and bitterness combined that she couldn't point out.
Lu Xinyi cast aside the flavors she already knew and focused on this unknown flavor. She was perfectly sure that it wasn't a vegetable. Could it be a fruit instead?
Thinking hard could what it was, Lu Xinyi tried to remember some fruits and berries that fit the description that has a sour and bitter taste. There were several she could think of, but only cranberries had left the same impression on her.
Fresh cranberries were both sour and bitter. It had less than four percent sugar. If one ever tasted a fresh cranberry or tried to drink a pure cranberry juice, one would know that it's hardly palatable.
