Everyone who prepares mashed potatoes this way makes a big mistake: never do this

Mashed potatoes are a classic dish that adds comfort on cold winter days. However, many people face a problem when mashed potatoes turn out to be lumpy or too liquid. This is due to a number of mistakes.

Rosemary Gill, director of the Boston-based Milk Street Culinary School, revealed the secret to perfect mashed potatoes in her TikTok video. She advises using milk correctly.

"When you boil the potatoes in water and then drain them, you lose all the starch that gives the mashed potatoes their tenderness and creamy texture," explains Gill. Instead, the starch-rich milk becomes "liquid gold," which adds silkiness and creaminess to the mashed potatoes, while replacing the need for heavy cream.

For even more convenience, Rosemary recommends mashing the potatoes directly in the pot, which reduces the amount of dishes to wash.

This simple trick has won over many cooking fans. One commenter called the author a "genius," while another noted: "My mashed potatoes are always perfect, and everyone asks me what the secret is."

Conclusion: replacing water with milk when making mashed potatoes preserves all the starch, providing an unrivaled texture and flavor.
