The 60-Second Quick Fixes

  • Too Thick? Gradually whisk in room-temperature stock or milk. Never use cold liquid, as it may cause the fats in the roux to seize.

  • Too Thin? Implement a beurre manié (equal parts raw butter and flour kneaded together) and whisk in small knobs until the desired thickness is achieved.

  • Grainy Texture? Pass the sauce through a fine-mesh chinois or sieve. This is the fastest way to achieve a professional, silky finish.
