Peel the potatoes and boil in salted water until tender but not falling apart, about 15–20 minutes. Drain and let cool slightly.
Tip Test with the tip of a knife — the slices need to hold their shape later. - 2
Preheat the oven to 200°C (392°F) / 180°C fan. Grease a baking pan with a little butter.
- 3
Slice the cooled potatoes into rounds about 1 cm thick. Arrange one full layer of potato rounds across the bottom of the pan.
- 4
Crumble the cheese evenly over the potato layer, spreading it to reach every edge of the pan.
- 5
Cover the cheese with a second layer of potato rounds.
- 6
Pour the melted butter evenly over the potatoes. Bake for about 25–30 minutes, until lightly golden.
Tip Traditionally, hot rendered fat was poured on here instead of butter for a richer flavor. - 7
Remove the pan from the oven. Whisk the eggs together with the sour milk and pour the mixture evenly over the potatoes. Return to the oven and bake for a further 10–15 minutes, until the topping is fully set and no longer wobbly in the center.

About This Recipe
There’s a particular kind of kitchen logic behind this dish: potatoes that are boiled first rather than raw, so they hold their shape through a second bake; cheese sandwiched between two layers instead of scattered on top, so a small amount reaches every bite; and a finishing pour of whisked egg and soured milk that sets into something between a glaze and a light custard. None of it requires a special technique — just an order of operations that early 20th century home cooks would have known by habit.
It’s the kind of recipe that turns a handful of pantry staples — potatoes, a soft cheese, some fat, eggs, and soured milk — into a dish substantial enough to carry a meal on its own, no meat required.
Why It Works
Pre-boiling the potatoes means they only need enough time in the oven to absorb the butter and warm through, rather than cooking from raw — which keeps the slices intact instead of collapsing into mush. The cheese layer, buried between two rounds of potato rather than sprinkled over the top, melts inward rather than browning and drying out. And because the egg-and-sour-milk mixture goes on only for the final 10–15 minutes, it sets into a light, tangy layer rather than scrambling or overcooking, the way it would if it baked the whole time.
Modern Kitchen Tips
Slice the potatoes to a consistent thickness so the layers cook evenly. If your cheese is very salty (a brined feta-style cheese, for example), taste a small piece before assembling — you may not need to salt the potato water as heavily. The dish is easiest to portion once it’s rested for five to ten minutes after the final bake, giving the egg topping a chance to firm up slightly.

The Story Behind This Recipe
Historical Context
Early 20th century home cooks often built simple potato bakes like this one from what was on hand — boiled potatoes, a soft cheese, rendered fat, and a finishing pour of egg and soured milk before a final bake. Sandwiching the cheese between two layers of potatoes let a modest amount season more of the dish, while the egg-and-sour-milk topping gave the surface a custardy, slightly tangy finish without a separate sauce.
Modern Kitchen Adaptation
The original method called for hot rendered fat poured over the potatoes; this version uses melted butter for accessibility, though lard remains a historically accurate substitute for a richer flavor. Sour milk, once a common pantry staple, is approximated here with cultured buttermilk or thin plain yogurt. Oven temperature was not specified in the source and is estimated at 200°C (392°F) / 180°C fan based on similar period potato bakes. Peeling the potatoes before boiling is added here for even slicing, since the source only specified boiling until tender. Nutrition values are estimated using standard USDA FoodData Central compositions for potato, brined cheese, butter, cultured buttermilk, and eggs.
