Ann Lander's Best Lemon Meringue Pie (With Never-Fail Meringue)

"One of the best recipes for lemon meringue pie! If you want a sky-high meringue, like the ones you see in bakery's, just use 6 egg whites (save yolks for another recipe), and double the sugar....I just use the same amount of cornstarch/water mixture when I use 6 egg whites. Prep time does not include making the meringue/cornstarch mixture. I have even made this pie using a graham cracker crust (the graham crust goes very well if topping with whip cream or Cool Whip), also if you prefer a very tart lemon pie add in another 2-3 tablespoons of fresh lemon juice. I most always prepare the crust and then fill with the filling the night before and let it thicken in the fridge overnight then top with the meringue the following day. Also in place of the meringue, I have many times topped it with Cool Whip or whipped cream, it it excellent that way also. Which ever way you choose to make it, it is a wonderful lemon pie recipe. *NOTE* if you are worried about scorching the bottom of the pan, then you can also make the filling in the microwave, here's how...in a large 8-cup microwave-safe bowl whisk together the sugar and cornstarch, add in all the remaining ingredients whisk to combine and microwave on HIGH for about 8 minutes (might take longer or less time) removing three times to whisk, make certain to cook the filling until hot, bubbly and thickened, then add in the 2 tsp vinegar and 3 tablespoons butter, this method works well and no scorched pans!"
