Preheat oven to 375°F.

In a saucepan over medium heat, whisk the water, cornstarch, sugar and salt.
Once the mixture comes to a boil, remove from heat and gradually add the cornstarch mixture to the egg yolks.
Return the mixture to the stove and on a low heat, whisking constantly, add the butter, lemon juice and lemon zest until mixture becomes thick, about 10 minutes.
Pour the mixture into your pre-baked pie crust.
In a standing mixer, beat the egg whites and cream of tartar until it forms soft peaks.
Slowly add the sugar to your egg whites until the peaks become hard.
