The story behind the recipe
Orange juice and grated peel give this sweet potato pie its direction. They join mashed sweet potato, milk, eggs, and a little butter in a single bottom crust. There's no cinnamon or vanilla in the filling; the citrus has room to be noticed.
Orange in a familiar pie
Abby Fisher's 1881 Sweet Potato Pie asks for potatoes boiled soft and mashed fine. Orange juice and grated peel go into the liquid, with yolks and whites beaten separately. Her instruction to use only a bottom crust leaves the filling open to view.

Juice and peel
The two parts of the orange make different contributions. Juice carries acidity and liquid into the mashed sweet potato; finely grated zest carries the peel's fragrance without large pieces. A finely mashed potato mixture gives that citrus somewhere to disperse, instead of leaving it concentrated in an occasional bite.
Sugar is left to taste in Fisher's passage. Our measured filling makes that decision explicit and keeps the orange alongside the potatoes, milk, and separated eggs. It makes one nine-inch pie with three large eggs, while Fisher's filling is written for two pies and five eggs. This is a chosen one-pie balance, not a literal half of every quantity.
The sweet potatoes are weighed after peeling, so a large irregular potato and several small ones can reach the same amount in the bowl. Draining them well also matters. Excess cooking water would join the milk and orange juice in a filling whose liquid has already been planned.
Pastry from the same book
Fisher's general pastry combines flour with butter and lard, adding cold water only until it holds together. Our crust draws on that flour-to-fat relationship. Cold-fat preparation, chilling, and blind baking supply the more detailed guidance needed for the plate and filling used here.
The pastry receives a head start in the oven before the moist filling goes in. It has its own butter allowance; the smaller quantity mashed into the potatoes belongs to the filling. Keeping those separate avoids using up the filling's butter during pastry work.
A plain bottom crust is enough. An elaborate top would obscure a pie whose unusual detail is inside, and Fisher doesn't ask for one. The egg-white folding stage also calls for a light hand: it should bring the beaten whites through the filling without leaving separate white patches.
A pie to start ahead
This isn't a last-minute dessert. The pastry chills, the cooked potatoes need to cool before the filling is mixed, and the baked pie needs time before slicing. Some tasks overlap, but the cooling can't be skipped just because the oven is free.
Fisher's book was published in San Francisco in 1881 and records her cooking knowledge through dictation. Our Southern Table feature follows the savory dishes beside this pie. For dessert, a plain slice leaves the orange-scented filling and the bottom crust to share the plate.

Instructions
Pastry
Mix the pastry dough
Mix the flour and pastry salt. Rub in the cold butter and lard until the mixture resembles coarse crumbs with a few small pieces of fat remaining. Stir in three-quarters of the listed cold water allowance, then add the remaining water a teaspoon at a time only until the dough holds together when pressed. Stop before it becomes sticky.
Chill the pastry and cook the sweet potatoes
Shape the dough into a disk, wrap, and refrigerate for 30 minutes. Meanwhile, put the sweet potato pieces in a saucepan, cover with water, and bring to a boil. Simmer for 15–20 minutes, until easily pierced. Drain thoroughly, mash smooth, and stir in the filling butter. Spread in a shallow dish and cool for about 20 minutes, until lukewarm.
Roll and line the pie plate
Heat a conventional oven to 200°C (400°F). Dust the rolling surface lightly with some of the reserved flour and roll the chilled pastry 3 mm thick, about 30 cm across for the original one-pie batch, using more of the reserved flour only if it sticks. Use the original ingredient quantities for one standard 9-inch pie plate, or divide a double batch between two matching plates. Line the plate or plates, ease the pastry into the corners, trim the excess, and crimp the rim. Refrigerate for 15 minutes.
Blind-bake the pastry shell
Set the pie plate on the baking sheet. Line the pastry with baking parchment and fill with pie weights or dry beans. Bake for 15–20 minutes, until the rim begins to color. Carefully lift out the lining and weights and bake for another 5 minutes, until the base looks dry. Reduce the oven to 175°C (350°F).
Filling and baking
Mix the sweet potato filling
Whisk the egg yolks, sugar, milk, orange juice, orange zest, and filling salt into the lukewarm sweet potato until smooth.
Whisk and fold in the egg whites
In a clean, dry bowl, whisk the egg whites to soft peaks. Fold one-third into the sweet potato mixture to loosen it, then fold in the rest just until combined.
Fill and bake the pie
Pour the filling into the warm pastry shell and return the pie, on its baking sheet, to the oven. Bake for 40–50 minutes, until the edges are set, the center has only a slight wobble, and the center reaches at least 160°F (71°C). Shield the pastry rim loosely with foil if it browns too quickly. Continue baking if the temperature or setting check is not met.
Cool, refrigerate and slice
Cool for at least 1 hour before slicing. Refrigerate within 2 hours of leaving the oven; if the room is above 90°F (32°C), refrigerate within 1 hour. Cut into slices for serving.

Source & assumptions
Estimated calories per slice (1/8 of the pie), using CoFID 2021 and USDA SR Legacy ingredients. Pastry retention is modeled from a uniform 30 cm disk lining a representative 9-inch-interior pie plate including its rim; boiled sweet potato uses published root-vegetable factors. Includes a small full-listed dusting-flour allowance. Pan shape, trimming and ingredients vary; not measured.
Recipe notes
When adjusting quantities
Original quantities make one 9-inch pie; double quantities make two. Fractional batches need a separate pan and baking plan. Keep the original batch for the specified pan and vary slice portions when serving fewer people. Times and temperatures do not scale automatically.
Original recipe notes
These notes describe the original recipe. Quantities mentioned here do not change when you adjust servings.
Pastry: The listed water is an allowance, not a requirement to use it all. Use only enough for the dough to hold together. The listed dusting flour is separate from the flour mixed into the pastry; use only what the surface needs.
Sweet potatoes: Weigh after peeling. Drain well so the filling does not carry excess cooking water. The orange juice and zest provide the intended citrus flavor; no cinnamon or vanilla is required.
Planning: These pan dimensions and baking directions describe the original one-pie batch. Make two separate pies when doubling, allowing space for both or baking in separate oven batches. A half or one-and-a-half ingredient batch needs its own pan-capacity and baking plan; no fractional-batch pan size or time is established here. For fewer diners, make the original pie and serve the number of slices needed. Extra pastry chilling is fine; the stated total is a planning estimate and will increase if the potatoes, pastry, or finished pie need longer to cool.
