Whisk eggs and egg yolks in a medium bowl until smooth.
4 large eggs, 2 large egg yolks
In a medium saucepan, combine lime zest, lime juice, honey, and butter. Heat over medium until the butter melts and the mixture begins to bubble at the edges. Remove from heat.
1 tablespoon lime zest, ½ cup fresh lime juice, ½ cup honey, 5 tablespoon butter
Gradually whisk ¼ cup of the lime mixture into the eggs to temper them. Then slowly whisk in the remaining lime mixture.
Return the mixture to the saucepan and cook over medium-low, stirring, until thickened and it coats the back of a spoon.
Strain through a fine mesh sieve into a bowl. If desired, stir in chlorophyll for a green color.
1 teaspoon unflavored chlorophyll
Pour the lime curd over the cheesecake filling in the tart, smoothing the top.
Refrigerate for 3–4 hours or overnight before serving.
