Ingredients:

  • All-Purpose Flour: 2 tablespoons (30 ml)
  • Unsalted Butter: 2 tablespoons (30 ml)
  • Cornstarch: 1 tablespoon (15 ml)
  • Cold Water: 2 tablespoons (30 ml)
  • Heavy Cream: 1/4 cup (60 ml)
  • Arrowroot Powder: 1 tablespoon (15 ml)
  • Lemon Juice: 1 teaspoon (5 ml)
  • Egg Yolks: 1-2 large eggs
  • Beurre Manié: Flour and butter mixture

Instructions:

  1. Choose Your Weapon: Determine which thickening method is best suited for your sauce. Consider the type of sauce, desired consistency, and flavour profile.
  2. The Roux: (For classic creamy sauces like béchamel or cheese sauce). Melt butter in saucepan. Whisk in flour until smooth. Cook over medium heat, stirring constantly, for desired colour (white, blond, brown). Gradually whisk in warm liquid (milk, stock) until smooth. Simmer, stirring occasionally, until thickened.
  3. Cornstarch Slurry: (For glossy, translucent sauces – great for Asian-inspired dishes). Whisk cornstarch and cold water together in a small bowl until smooth. Bring sauce to a simmer. Slowly whisk in the slurry. Simmer, stirring constantly, until thickened.
  4. Heavy Cream: (For rich, decadent sauces – be careful not to boil!). Bring sauce almost to a simmer. Stir in heavy cream. Heat gently, stirring, until thickened. Important: Do not boil the sauce after adding cream!
  5. Arrowroot: (Similar to cornstarch, but with a clearer finish). Mix arrowroot with cold water to form a slurry. Bring sauce to a simmer. Whisk in the slurry and simmer until thickened.
  6. Egg Yolks (Liaison): (For rich, velvety sauces like hollandaise or carbonara – requires careful temperature control). Whisk egg yolks with a little sauce in a bowl. Temper the egg mixture: slowly drizzle warm (not hot!) sauce into the egg mixture, whisking constantly. Return the tempered mixture to the saucepan. Cook over low heat, stirring constantly, until thickened and coats the back of a spoon. Important: Do not boil or the eggs will scramble! Target temperature: 170-180°F (77-82°C)
  7. Beurre Manié: (For last minute quick thickening without cooking flour). Combine flour and softened butter with a fork until smooth. Whisk pea-sized dabs into the simmering sauce until it reaches the desired thickness
  8. Incorporate Carefully: Add your chosen thickening agent gradually, whisking constantly to avoid lumps.
  9. Simmer Gently: Allow the sauce to simmer gently, stirring occasionally, until it reaches your desired consistency.
  10. Taste and Adjust: Season the sauce to taste. You may need to add more salt, pepper, or other seasonings to balance the flavours.
