These are so easy and so fast, my two favorite things. They have an amazing zest taste to them, My kids loved eating them and they would make for great party food or Holiday food.
In a small mixing bowl, add the sweetened condensed milk, lime juice, zest, powdered sugar, egg yolks.
Mix well, until all of the eggs are blended in.
Then fill the shells with the filling.
As you fill the tarts place them in your air fryer tray or basket.
Place the tray into the oven/air fryer.
Set the temperature to 320 degrees F, for 5 minutes.
Let them cool about 10 minutes, before adding whipped cream (if desired)
Plate, serve and enjoy!
