INGREDIENTS
- 1 cup granulated sugar
- 2 tablespoons cornstarch
- 1/4 teaspoon salt
- 1 cup water
- 1/2 cup fresh lemon juice (approximately 3-4 lemons)
- 2 tablespoons lemon zest (from 2 lemons)
- 2 tablespoons unsalted butter
- 1 large egg yolk, lightly beaten
- Optional: 1-2 drops of yellow food coloring for enhanced color
INSTRUCTIONS
In a medium saucepan, whisk together the sugar, cornstarch, and salt until well combined. Gradually add the water while continuing to whisk, ensuring no lumps remain. Place the saucepan over medium heat and cook the mixture, stirring constantly, until it begins to thicken and becomes translucent, approximately 3-4 minutes.
Once the mixture has thickened, reduce the heat to low and add the fresh lemon juice and zest. Continue to cook for an additional 2 minutes, stirring frequently. Remove the saucepan from the heat and whisk in the butter until it melts completely and is fully incorporated into the sauce.
To temper the egg yolk, take a small amount (about 2 tablespoons) of the hot lemon mixture and slowly add it to the beaten egg yolk while whisking continuously. This prevents the egg from curdling when added to the hot sauce. Once tempered, gradually whisk the egg yolk mixture back into the saucepan with the remaining sauce.
Return the saucepan to low heat and cook for an additional 2 minutes, stirring constantly. The sauce should coat the back of a spoon when ready. If using food coloring, add it now and stir to distribute evenly.
Remove from heat and allow the sauce to cool slightly before transferring to a glass jar or container. The sauce will continue to thicken as it cools.
