Old-Fashioned Buttermilk Pie
Buttermilk pie is the queen of the desperation pies — the ones our grannies baked in the lean months, when the orchard was bare and the flour barrel low, from what the springhouse always had: buttermilk, eggs, butter and a scoop of sugar. Out of nearly nothing comes something lovely — a tangy-sweet custard under a golden, faintly crackled top, with a whisper of lemon and vanilla running through it. Nobody at the table ever called it desperate.
There are only two things to know, and they're the same rules as any custard pie. First, pull it from the oven while the centre still wobbles like set jelly — it finishes setting as it cools, and a pie baked firm in the oven will weep and curdle on the worktop. Second, don't fret when it puffs up proudly and then sinks flat as it cools; that gentle settle is exactly what's meant to happen.
The filling is one bowl and a whisk — no mixer, no water bath, no fuss. Blind bake the case so the bottom stays crisp under the wet filling, pour it in, and let the oven do the quiet work. It's humble as anything, and always the first pie to disappear.
Old-Fashioned Buttermilk Pie
Tangy-sweet custard with a golden crackled top — the classic Southern desperation pie from humble staples.
Ingredients
- 1 shortcrust pastry case, 23 cm (about 320 g pastry), unbaked
- 300 g caster sugar
- 3 tbsp plain flour (about 25 g) and ¼ tsp fine salt
- 3 large eggs, at room temperature
- 115 g butter, melted and cooled slightly
- 250 ml buttermilk, at room temperature
- 1 tbsp lemon juice, zest of ½ lemon and 1½ tsp vanilla extract
- freshly grated nutmeg, for the top (optional)
Method
- Blind bake. Line a 23 cm pie tin with the pastry, crimp the edge and chill 20 minutes. Bake at 200°C (fan 180°C / gas 6) — 15 minutes with paper & baking beans, 5 minutes without — until dry and pale gold. Turn the oven down to 170°C (fan 150°C / gas 3).
- Whisk. Whisk the sugar, flour & salt, then whisk in the eggs until completely smooth. Whisk in the melted butter, then the buttermilk, lemon juice, zest & vanilla. The filling is thin as cream — that's right.
- Fill. Set the case on a baking tray, pour in the filling and grate a little nutmeg over the top.
- Bake. 45–55 minutes, until deep golden on top and set at the edges but with a wobble like set jelly in the middle. It will puff proudly — don't wait for it to firm up in the oven. If the top browns too fast, lay foil loosely over it for the last 15 minutes.
- Cool. Cool completely on a rack, at least 2 hours — it settles flat and finishes setting as it cools. Serve at room temperature, or chilled for cleaner slices.
Granny never trusted the clock — she trusted the shimmy. Slip a knife in halfway between the edge and the centre: if it comes out clean there while the middle still trembles, the pie is done.
Tips for the silkiest custard
Watch the wobble
Pull it when the centre trembles like set jelly. A middle baked firm in the oven means a cracked, weepy pie on the worktop.
Blind bake the case
Fifteen minutes with beans keeps the bottom crisp under such a wet filling — skip it and you risk a soggy base.
Everything at room temperature
Cold buttermilk seizes the melted butter into waxy flecks. Let the eggs & buttermilk lose their chill for a silky, even custard.
Questions, answered
What is the difference between buttermilk pie and chess pie?
They are close cousins, but chess pie is thickened with cornmeal (and usually a splash of vinegar), which gives it a denser filling and a slightly chewy, gritty top. Buttermilk pie uses only a spoonful of flour and much more buttermilk, so it bakes up softer, silkier and noticeably tangier — closer to a true custard. There is no cornmeal in this recipe.
Why did my buttermilk pie crack or turn watery?
Overbaking. When the custard cooks too far, the eggs seize and squeeze out their moisture, which cracks the top and leaves liquid pooling beneath. Take the pie out while the centre still wobbles like set jelly — it firms up completely during the 2 hours of cooling.
Can I make buttermilk pie ahead or freeze it?
It is a fine make-ahead pie: bake it the day before, cool completely, then cover and refrigerate — it keeps 3 days and slices more cleanly when cold. Freezing works at a pinch (wrap tightly, freeze up to 1 month, thaw overnight in the fridge) but the custard loses a little silkiness, so the fridge is better.
Can I use ordinary milk instead of buttermilk?
Not on its own — the tang is the whole point, and the acidity helps the custard set. Stir 1 tablespoon of lemon juice or white vinegar into 250 ml of whole milk and let it stand 10 minutes until slightly thickened, then use it exactly as you would buttermilk.
