Ingredients
Method
- In a saucepan over medium heat, whisk together brown sugar, flour, and salt. Cook slowly to help the butterscotch flavor develop.
- Gradually pour in milk while whisking constantly to avoid lumps. Continue cooking until smooth and warmed through.
- Add butter and stir until melted completely.
- Temper the egg yolks by slowly adding some of the hot mixture to them while stirring constantly. Pour yolks back into the saucepan.
- Cook 2–3 more minutes until thick and pudding-like.
- Remove from heat and stir in vanilla extract.
- Pour filling into the pre-baked pie crust and let cool slightly.
- For the meringue, beat egg whites and cream of tartar on low speed, gradually increasing until soft peaks form.
- Slowly add sugar and continue beating until stiff, glossy peaks form.
- Spread meringue over the warm butterscotch filling, sealing the edges to the crust.
- Bake at 350°F (175°C) for 12–15 minutes or until the meringue is golden brown.
Notes
For best texture, cool the pie completely before slicing. Store leftovers in the refrigerator.
