Sensationally Smooth and Simple Vanilla Custard Pie
You can use 1 cup cream with 1 1/4 cups milk instead of all milk, if you like. Substitute 1 drop of edible lemon essential oil for the lemon zest if you want.
The egg wash apparently keeps the crust from getting soggy. May also do egg wash and pre-bake for 7 to 9 minutes for extra flaky crust.
Transfer the pie very carefully to the preheated oven. Any spill over will be messy and burn. Trust me here, be slow and careful. I cover the edges with a crust shield to help prevent it from getting too brown.
It is really rather forgiving and can be tweaked to your tastes, preferences, and flavors. Try adding a bit of coconut or making with canned coconut cream. Just don't overcook or cut before it's cooled, and keep the ratios of wet to egg about the same.
