# Expert Advice:

01 -
  • It takes 15 minutes total and teaches you the most useful kitchen skill that transforms dozens of dishes.
  • One batch feeds four people and tastes indulgent despite being humble butter, milk, and flour.
  • Unlike heavy cream sauces, this one feels light but still coats pasta and vegetables like silk.
02 -
  • The flour must cook in hot butter for a minute or two before milk touches it, or your sauce tastes starchy and flat.
  • Low, slow whisking while adding cold milk prevents lumps better than rushing—patience is the real secret ingredient here.
03 -
  • Warm your milk slightly before adding it—cold milk can shock the roux and cause lumps.
  • Medium heat is where this sauce belongs; too-high heat can break the emulsion and make it grainy.
