Crush saltines well, but not into a fine powder. Add sugar and butter and mix together until you can squeeze some of the mixture in your hand and it holds a shape.
Press saltine mixture into pie dish and chill for a few minutes.
Bake bake pie crust at 350º for about 15 minutes for a crispy crust, then while it cools, mix pie filling.
Mix together egg yolks, lemon juice, and sweetened condensed milk. Make sure you mix this well and that there are no lumps.
Pour pie filling into crust and bake in 350º oven for about 17 minutes.
Remove from oven and let cool a bit, then transfer to the refrigerator and let it chill completely. This pie should be served very cold.
Serve with homemade whipped cream or your favorite whipped topping.
Notes
NOTE: If you prefer, you can make a meringue topping for the pie instead of using whipped cream or other whipped topping. Watch my Chocolate Pie video for instructions on how to make meringue topping. https://youtu.be/6G-1TsIillM
