Adding peanut butter makes the aroma more balanced, while sesame paste carries a hint of sweetness.
In earlier years, due to material shortages, sesame paste, which was popular in Beijing, was in short supply, so state-owned sauce factories would mix peanut butter into sesame paste as a substitute.
This sauce was called peanut sauce.
Compared to the slightly bitter pure sesame paste, peanut sauce had the sweetness of peanuts, making it more appealing to children, and it became an unforgettable taste in many people's memories.
Actually, with the current abundance of materials, there's no need to add peanut butter to sesame paste anymore.
But Lin Xu likes the sweet richness of peanut butter, so he adds some.
Besides peanut butter, to improve the texture of sesame paste, you can add Sprite to thin it.
Sprite has sweetness and is rich in carbonation, which can create lots of dense small bubbles in the sesame paste. These bubbles give a strong feeling of satisfaction when eaten.
