Combine the mango puree, whole eggs, egg yolks and granulated sugar in a saucepan.
1 Cup Mango puree (from fresh or defrosted mangos), 2 Large Eggs, 2 Large Egg Yolks, ½ Cup Granulated Sugar
Heat over medium-low, stirring constantly. If you stop stirring, the eggs could cook too fast and make the curd lumpy instead of smooth.
Continue to heat for 3 - 5 minutes until mixture thickens and begins to simmer (temperature will be approximately 180 ℉).
Remove saucepan from the heat and stir in cold butter. Continue stirring until all the butter has melted.
½ Cup Unsalted Butter, cold and cut into ⅓" cubes
Optional if any lumps formed in curd: Strain curd through a sieve placed over a bowl to remove any lumps.
Press plastic wrap over the top of the curd to prevent a skin from forming. Place in refrigerator until cooled completely.
