Sweet Potato Pie

North Carolina's pie is one cup of sweet potato, butter, eggs and nutmeg, and the oldest printed version in the state has no cinnamon in it at all.

The Raleigh Cook Book of 1907 gives the whole thing in six lines. "Sweet Potato Pie — 1 cup baked or boiled sweet potato," then milk, eight tablespoons of butter, three eggs, two cups of sugar and nutmeg; the method is to mix the sugar and potato, warm them on the stove and mash them with the butter, beat the eggs with the sugar, add the potato through a sieve or a potato masher, flavour with nutmeg and "bake on crust." It makes two pies. What is not in it is as useful as what is: no cinnamon, no cloves, no vanilla, no condensed milk, no marshmallow, none of the things a sweet potato pie is assumed to contain. The quantity of milk is the one thing the scan will not give up — the line reads "114 cups", a fraction lost somewhere between the page and the camera — so that number here is mine, not theirs. Everything else is the 1907 pie, with the sugar cut by a quarter, because two cups across two pies was sweeter than most people now want.

Warming and sieving the potato is the step that looks fussy and is not. Baked sweet potato is fibrous, and a masher leaves strings that show up as threads in a finished slice; the 1907 book already knew to press it through. The variety matters too, and the federal record explains what to look for: USDA Farmers' Bulletin 999, "Sweet-potato growing," revised in 1923, says that the northern markets prefer a dry, mealy potato of the Jersey type while "the southern markets demand a moist-fleshed variety," naming the Nancy Hall and the Porto Rico as the most popular, with the Dooley and the Pumpkin "Yam" also selling readily. That is why the orange, wet-fleshed roots sold as yams make this pie and the pale mealy ones do not. Farmers' Bulletin 970 of 1918 adds the part that happens before you buy them: newly dug sweet potatoes are held at 80° to 85°F with plenty of ventilation for ten days or two weeks, the curing that turns a raw root into something worth baking. The Federal Writers' Project, listing in 1939 what a North Carolinian will not do without, put "sweet yams" in the same breath as country butter and chopped barbecue.

Why this version works

Nutmeg alone. Cinnamon dominates anything it is put into, and the earliest North Carolina print of this pie does not use it. Grate whole nutmeg over the filling at the end and you can still taste the potato, which is the entire argument for making sweet potato pie rather than pumpkin.

Baked, never boiled. The 1907 recipe allows either, and either works, but they are not the same pie. A sweet potato baked whole loses water and concentrates; boiled, it takes water on and dilutes everything you add afterwards. Bake them until they are collapsing and leaking syrup at the ends, then scoop the flesh out hot.

Warm the potato with the butter. Butter stirred into hot potato emulsifies and disappears; stirred into cold potato it stays as specks that melt out in the oven and leave a greasy layer under the surface. This is the order the old recipe gives and it is the reason the filling sets smooth.

Through a sieve, not just a masher. Sweet potato has fibre running its length. Pressing the warm flesh through a medium sieve takes thirty seconds a potato and is the difference between a filling that slices like custard and one that pulls apart in threads.

Ingredient notes

Milk: three quarters of a cup of whole milk. Evaporated milk, which is what most twentieth-century versions of this pie use, makes it denser and slightly caramelised and is entirely defensible — just say which one you used, because the difference is noticeable.

Crust: one nine-inch single crust, chilled hard, blind-baked. An all-butter shell browns better and a shortening shell stays crisper under a wet filling; both fail the same way, which is by going soggy if the filling goes into raw pastry.

Sugar: three quarters of a cup of light brown sugar, against the cup per pie the 1907 book used. Brown sugar is a choice, not a restoration; white sugar tastes cleaner and lets the nutmeg through more clearly. Either way, do not go above a cup unless you are cooking for someone who grew up on the older, sweeter version.

Sweet potatoes: two pounds of the orange, moist-fleshed kind — Beauregard and Covington are what most American shops sell now, and both are in the line the 1923 bulletin describes as what southern markets demand. Pale, dry, mealy varieties give a sandy filling that needs more milk and tastes of less.

Step by step

  1. Bake the potatoes. Prick the sweet potatoes, set them on a foil-lined tray and bake at 400°F for 55 to 70 minutes, until they are soft all the way through and syrup is leaking out of the ends. Split them and scoop the flesh out while hot; you want 2 cups packed.
  2. Blind-bake the shell. Drop the oven to 375°F. Line the chilled crust with foil and pie weights, bake 20 minutes, lift the foil and bake 6 to 8 minutes more until the base looks dry and pale gold. Leave it on a rack while you mix.
  3. Warm the potato with butter and sugar. Put the hot potato flesh in a pan with the butter and the brown sugar over low heat and stir for 2 minutes, until the butter has vanished into it and the sugar has dissolved. Press the mixture through a medium sieve into a bowl.
  4. Finish the filling. Beat the eggs and the extra yolk with the salt, stir them into the warm potato, then the milk, then the nutmeg. The filling should pour thickly, like a heavy batter; if it is stiff enough to hold a spoon upright, add milk two tablespoons at a time.
  5. Bake. Pour into the shell, smooth the top, and bake at 375°F for 15 minutes, then at 325°F for 30 to 40 minutes. It is done when the outer two inches are set and the middle three inches still move as one piece when you nudge the tin.
  6. Cool completely. Cool on a rack at least 2 hours before cutting. The centre finishes setting as it cools, and a pie cut warm collapses onto the plate no matter how well it was baked. Grate a little more nutmeg over the top just before serving.
A cracked top means it was in the oven past the wobble, and no amount of cooling closes the crack. Cover it: whipped cream over the whole surface, or a dusting of nutmeg and a ring of cream round the edge. The slices will still taste right, because a slightly over-baked sweet potato filling goes firm rather than curdled. If it is the base that failed and the pastry is damp, serve the pie from the tin with a spoon and call it a pudding — the older Southern books print the same mixture without a crust for exactly that reason.

Storage and make-ahead

Keeps 4 days covered in the fridge and is better on the second day, when the nutmeg has spread through the filling. Bring slices back to room temperature before eating; straight from the fridge the butter is firm and the flavour is flat.

Freezes poorly. The custard weeps on thawing and the crust turns to cardboard. If you need to work ahead, bake the potatoes and refrigerate the sieved purée for up to 3 days, then warm it with the butter and finish the filling on the day.

What to serve with it

Unsweetened whipped cream, and nothing else on the plate. This is the last course of a barbecue table and it follows vinegar and pepper well precisely because it is not very sweet. Coffee rather than dessert wine; the nutmeg fights anything fortified.

Questions readers ask

Why no cinnamon?

Because the earliest North Carolina printing of this pie does not call for it. The Raleigh Cook Book of 1907 flavours with nutmeg and stops there, and having cooked it both ways, the reason is obvious on the fork: cinnamon turns sweet potato pie into a generic spiced custard. Add a quarter teaspoon if you want it, and know you are adding it.

Is this the same as pumpkin pie?

Same structure, different behaviour. Sweet potato carries far more starch, so the filling sets firmer and slices cleaner, and it needs less egg for the same body. It also tastes sweeter at the same sugar, which is why the sugar here comes in below the 1907 measure and still reads as a dessert.

Can I use canned sweet potato purée?

You can, and the pie will be flatter. Canned purée is packed wet, so it dilutes the filling and brings none of the concentration that baking gives; if you use it, drain it in a sieve for half an hour and cut the milk to half a cup. Canned yams in syrup are a different product again and will make the pie cloying.

Should the potatoes sit before I use them?

They usually already have. Farmers' Bulletin 970 describes the trade practice of holding newly dug roots at 80° to 85°F for ten days or two weeks to cure them, and anything from a shop has been through it. If you have just dug them out of a garden, give them a week somewhere warm before baking — straight from the ground they are watery and taste of raw starch.
