Directions

  1. Heat the milk until it begins to simmer.
  2. In a separate saucepan, melt the butter and add the flour.
  3. Cook for three or four minutes, stirring constantly with a wooden spoon, without letting it brown: this step is crucial to avoid a floury taste.
  4. Remove from the heat and slowly pour in the warm milk, whisking vigorously to achieve a smooth, lump-free texture. ≈ 3 min
  5. Season, return to the pan, and cook for fifteen minutes.
