Step 1: In a large saucepan combine sugar and cornstarch. Whisk in milk and lemon juice until well combined. Over medium heat, cook, stirring constantly, until mixture becomes thick and bubbly. Reduce heat and cook for approx 2 minutes, stirring constantly.
Step 2: Add a spoonful of the hot lemon mixture to the eggs and stir well. Repeat several times until the egg mixture becomes thick and creamy like the lemon mixture (you don't want the eggs to get cooked when added to the hot mixture). Pour egg mixture into the saucepan, stirring well to combine. Bring mixture back to a simmer and cook a couple more minutes. Stir well and remove from heat.
Step 3: Add butter and lemon zest and stir until butter is melted. Allow mixture to cool and gently stir in sour cream. Add sour cream/lemon mixture to the pie shell and cool in the refrigerator for at least 3 hours before serving.
Step 4: In a mixing bowl combine whipping cream and 4 Tbsp. confectioners. Beat on medium-high speed until stiff peaks form (or desired consistency). Cover and refrigerate until ready to serve.
Step 5: Top individual pie slices with whipped cream before serving.
