Apple Bourdelaise Gastrique Recipe

Apple Gastrique

1. 1

   Prepare apples

   Peel, core and dice enough Granny Smith apples to measure 2 cups. Use firm tart apples; dice into roughly 1/4- to 1/2-inch pieces so they break down evenly during cooking.

2. 2

   Caramelize sugar

   In a medium saucepan over medium heat, add the 1 cup granulated sugar in an even layer. Without stirring initially, let the sugar start to melt at the edges. Once edges melt (about 2–3 minutes), gently swirl the pan occasionally or stir with a heatproof spatula to encourage even caramelization. Cook until the sugar reaches a deep amber color but is not burnt (about 6–8 minutes).

3. 3

   Deglaze with liquids

   Carefully add the 60 ml water to the caramel — it will sputter vigorously; stand back and use a long-handled utensil. Stir to dissolve any hardened sugar. Immediately add the 120 ml apple cider vinegar and the 45 ml bourbon. Stir to combine and allow the mixture to deglaze the pan, simmering gently for 1–2 minutes to marry flavors and burn off some alcohol.

4. 4

   Cook apples

   Add the diced apples to the pan along with 1 tablespoon fresh lemon juice and the optional star anise if using. Reduce heat to medium-low and simmer, stirring occasionally, until the apples soften and the liquid reduces to a glossy, slightly thickened sauce, about 10–12 minutes. Use the back of a spoon to break down some apple pieces — leave a mix of soft pieces and some texture for a gastrique with body.

5. 5

   Finish and season

   Once the mixture has thickened to a sauce consistency (should coat the back of a spoon), remove from heat. Stir in 1 tablespoon unsalted butter until melted and incorporated for gloss and mouthfeel. Season with 1 teaspoon fine sea salt and 1 teaspoon freshly ground black pepper to taste. Remove and discard the star anise if used. Taste and adjust acidity with a dash more lemon juice or vinegar if needed.

6. 6

   Strain or blend (optional)

   If a smooth gastrique is desired, let the mixture cool slightly then transfer to a blender and puree until smooth, or pass through a fine-mesh sieve, pressing solids to extract sauce. Return to pan and warm briefly before serving. For a chunky finish, skip this step.

7. 7

   Store and serve

   Use the gastrique warm spooned over roasted pork, duck, chicken, or drizzled on roasted vegetables. Store in an airtight container in the refrigerator for up to 7 days; rewarm gently before using.
