🛒 Ingredients

1 servings

1
  • 400 g (2 cups) granulated sugar
  • 240 ml (1 cup) hot water
  • 1 tablespoon lemon juice
  • 1 pinch of fine salt

Directions

  1. 1

    Pour the sugar into a heavy-bottomed saucepan. Heat over medium heat without stirring until the edges begin to melt and turn golden.

  2. 2

    Add the lemon juice and stir gently with a heatproof spatula. Continue cooking until the caramel reaches a deep amber color throughout.

  3. 3

    Remove from heat and carefully pour in the hot water (stand back to avoid splashes). Add the pinch of salt and stir to combine.

  4. 4

    Return to low heat and simmer for 3 to 5 minutes, stirring gently, until all crystals dissolve and the sauce is slightly syrupy.

  5. 5

    Immediately pour the hot caramel into your flan mold and tilt to coat the bottom evenly. Allow to cool before adding the flan batter.

💡 Chef's Tip

Avoid stirring the sugar at the very start to prevent crystallization. Use a light-colored pan so you can monitor the caramel color accurately. Act quickly once ready — caramel hardens fast as it cools.
