• Begin by taking a moment to separate the 4 eggs** you will need for this recipe. Place 1 egg yolk in a small bowl (for the pie crust.) Place 3 egg yolks in another small bowl (for the pudding). Place all 4 egg whites in a large bowl or stand mixer that is very clean and grease free (for the meringue. The whites need to sit at room temperature for at least 30 minutes before you beat them, that's why we're doing this now.)
• Now make the pie crust. Fill a small bowl with ice and water so it is ready when you need it.
• In a large bowl, whisk together flour, sugar, and salt.
• Use a pastry cutter or fork to cut in the butter-flavored Crisco.*  Cut with the pastry cutter until it looks like coarse crumbs. Don't overdo it! You want pea-size chunks of shortening. 
• In the small bowl with 1 egg yolk, whisk in 1/4 cup ice water, then add it to the flour mixture. Stir until it with a fork until it is just coming together, then use floured hands to knead it a few times (only to make it come together). Divide the dough in half. 
• Shape one half into a disc, put it in a ziplock, and stick it in the freezer. Save it for another pie another day! 
• Generously sprinkle flour onto a sheet of parchment paper or a pastry cloth (or the counter). Roll the dough with a rolling pin, using as much flour as you need so that it doesn't stick. Invert the parchment paper onto a 9-inch pie pan and gently peel off the paper. (Or if you are not using paper, roll it up gently on the rolling pin and transfer to the pie pan.)
• Arrange the pie crust and fold any excess crust underneath (I don't believe in trimming it off. Just fold it under!) Crimp as desired. I used a fork, easy peasy. Use the same fork to prick the bottom and sides of the crust all over.
• Place the pie pan in the freezer or fridge. It should chill for at least 30 minutes.
• Preheat your oven to 450 degrees F. 
• When your oven is very hot and your pie crust is very cold, line the bottom of the pie crust with foil. Fill with pie weights, coins, dried beans or rice, whatever you have. This will prevent bubbles from rising up. 
• Bake at 450 for 8 minutes. Remove the foil and pie weights. Return to the oven and bake for another 7-8 minutes, until the bottom of the crust is no longer shiny.
• Remove from the oven and set aside. Lower your oven temperature to 325 degrees F.

Only once your pie crust is completely baked should you start making the meringue and filling. I made them simultaneously, because this is just how I make my life exciting, but if you have someone to help you, even better. The reason you want them done at the same time is because the meringue has to be placed on top of the filling when it is HOT, not warm, HOT. If you are going solo, make the meringue first:

• For the meringue: In a liquid measuring cup, add 1/2 cup COLD water and 2 teaspoons cornstarch. Whisk together well until there are no lumps. Microwave on high for 30 seconds, whisk again, then microwave for another 30 seconds, until it has formed a glossy gelatinous liquid. 
• You should have 4 eggs whites in a large bowl that have been sitting at room temperature for at least 30 minutes. Add 1 teaspoon vanilla and 1/2 teaspoon cream of tartar. Beat (with your whisk attachment, if you are using a stand mixer) on medium speed for about 1-2 minutes, until soft peaks form (the tips should just be starting to curl when you lift the beaters.) 
• Turn the mixer on high and add 1 tablespoon of sugar at a time, making sure that each addition of sugar is fully incorporated before adding the next tablespoon. (8 tablespoons is 1/2 cup)
• Don't turn off the mixer. Slowly pour in the warm water/cornstarch mixture. Continue beating until stiff, glossy peaks form when you lift the beaters out. The tips will stand up straight and not droop at all. See photo.
• For the butterscotch pudding: In a medium saucepan, (off heat) whisk together brown sugar, 1/2 teaspoon salt, and 2 tablespoons + 1 teaspoon cornstarch. Add the milk, cream, and the 3 egg yolks you set aside earlier. Whisk it all together.
• Set the pan over medium heat. Bring to a boil, whisking frequently. Once it boils, set a timer for 1 minute, whisking constantly. Your spoon should leave marks in the top of your pudding. 
• Remove from heat and add 2 tablespoons butter and 1 teaspoon vanilla. Stir until melted.
• Pour the pudding into the pie crust and spread evenly. (If your meringue is not ready yet, keep the pudding in the saucepan and stir occasionally so that you don't get a film on top. Keep warm) 
• Beat the meringue on high one last time, and QUICKLY spread the meringue on top of the HOT pudding. The meringue should touch the pie crust to completely seal the pudding.
• Swirl or dollop the top or your meringue however you like.
• Bake at 325 degrees F for 25-28 minutes. The top of your meringue should be browned (not black, I did that with a kitchen torch later). If you really want to avoid your meringue weeping, use an instant read thermometer to test the center of the meringue (hold it at an angle). It should read 160 degrees. 
• Let the pie cool on a wire rack on the counter for about 1-2 hours. Transfer to the fridge and chill completely 3-6 hours.
• If you want the darker toasting on the meringue, use a kitchen torch just before serving. 
• Serve with a small sprinkle of brown sugar and some chopped candied pecans.
• Cover the pie for longer storage in the fridge. I use my grandma's old trick of poking toothpicks into the top of the pie and putting plastic wrap over the top, so you don't ruin your meringue.
