I am rather new to pie baking (outside of the occasional pumpkin or cheesecake). I bought Ashley English's book "A Year of Pies" and tried a few of her recipes. Two that have not come out well are the Limoncello Lemon Meringue Pie and the Minty Chocolate Cream Pie. In both cases, the filling ended up runny. I followed her instructions, but still had unsatisfactory results. The filling recipes include the following: Limoncello Lemon Meringue Pie 1 Cup Water 1 Cup Granulated Sugar 1/3 Cup Cornstarch 1/4 Teaspoon Sea Salt 5 Large Egg Yolks 2/3 Cup Lemon Juice 1/3 Cup Limoncello 4 Tbs Unsalted Butter Mix ingredients and pour into pie shell. Bake at 350 F for 40-45 minutes Minty Chocolate Cream Pie 2-1/2 Oz. Sweetened Baking Chocolate 3/4 Cup Granulated Sugar 3 Tbs Cornstarch 1/2 Tsp Sea Salt 2 Cups Whole Milk 3 Large Egg Yolks 3 Tbs Unsalted Butter 2 Tsp Vanilla Extract Main ingredients to be cooked at a boil for a couple of minutes, then use a 1/2 cup of the mixture to proof the egg yolks. After that, they are poured into the pan, mixed, and cooked for another couple of minutes. The Butter, Vanilla, are added, then the mixture is poured into a pie crust and the pie is refrigerated. Both ended up as a very soupy mess, rather than the firm fillings I've seen. Can anyone help? Thanks in advance!!!
