Step‑by‑Step Instructions for Grandma’s Secret Sweet Potato Pie
Step 1: Prepare Sweet Potatoes
Begin by peeling and cubing 2 medium sweet potatoes. Place them in a large pot, cover with water, and bring to a boil over medium-high heat. Cook for about 30 minutes, or until they are fork-tender. Once cooked, drain the sweet potatoes and mash them until smooth and creamy using a potato masher or a fork, ensuring there are no lumps for your filling.
Step 2: Make Filling
In a mixing bowl, combine the smooth mashed sweet potatoes with ¾ cup granulated sugar, ¾ cup evaporated milk (or coconut cream for a dairy-free version), 2 large eggs, 1 teaspoon vanilla extract, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, and a pinch of salt. Mix thoroughly until the filling is well combined and has a creamy consistency, ensuring all ingredients are evenly distributed.
Step 3: Assemble Pie
Prepare a pre-made pie crust by placing it in a 9-inch pie dish. Pour the creamy sweet potato filling into the crust, smoothing the top with a spatula for an even surface. Ensure the filling is well centered and leveled to create a beautiful presentation. This step is crucial in making Grandma’s Secret Sweet Potato Pie a treat for both the eyes and taste buds.
Step 4: Bake
Preheat your oven to 350°F (175°C). Once heated, carefully place the pie into the oven and bake for approximately 50 minutes. The pie is done when the filling is set and a toothpick inserted into the center comes out clean. Keep an eye on it towards the end, ensuring the crust doesn’t brown too much.
Step 5: Cool and Serve
Once baked, remove the pie from the oven and allow it to cool on a wire rack for at least 1 hour. This cooling time helps the filling to set perfectly, making slicing easier. Serve slices of Grandma’s Secret Sweet Potato Pie as is, or elevate the experience with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.
