Tourteau fromager — Poitevin black-domed goat-cheese cake
Tourteau fromager is recognisable before it is cut: the top rises into a rounded, almost startlingly black shell, while the interior remains pale, soft and lightly aerated. That contrast is the identity of the cake, not a defect to disguise. The recipe therefore uses a short burst of very high heat followed by a lower-temperature finish.
Fresh, well-drained goat cheese is mixed with yolks, flour, milk and sugar, while the whites are whipped separately. The mixture is folded rather than beaten after the whites go in. Excess aeration or rough mixing can make the rise erratic and the structure fragile, so the batter should look light and even rather than foamy.
The first oven stage builds the dark dome; the second sets the centre. The cake is safe and properly set when the interior reaches 71 °C, but it still needs a long undisturbed cool before unmoulding. Cutting too early compresses the tender interior and can encourage the dome to collapse.
