Method
- Butter the baking dish well, right up the sides. Spread the softened butter generously over one side of every bread slice, then cut each slice in half on the diagonal to make triangles.
- Arrange a first layer of triangles in the dish, butter side up and overlapping like roof tiles. Scatter over half the sultanas and half the lemon zest.
- Lay the remaining triangles over the top in the same overlapping way, butter side up, and tuck the rest of the sultanas and zest between the slices rather than on top, where they would scorch.
- Warm the milk and cream in a saucepan over medium heat until steam rises and the edges just tremble. Do not let it boil.
- In a large bowl whisk the eggs, egg yolk, half cup of sugar, vanilla and salt until smooth and pale, about 1 minute.
- Pour the hot milk into the eggs in a slow stream, whisking constantly, until you have a thin, even custard.
- Pour the custard slowly and evenly over the bread, letting it soak in before adding more. Press the top slices down gently with your fingertips so they drink it up, then let them float back.
- Leave the dish to stand at room temperature for 30 minutes. The bread should feel heavy and saturated, with only a shallow pool of custard left around the edges. Heat the oven to 350 F toward the end of the soak.
- Sprinkle the remaining tablespoon of sugar over the surface and grate nutmeg generously across the top.
- Bake uncovered on the middle rack for 35 to 45 minutes. It is done when the exposed corners are deep golden and crisp, the custard is set around the sides, and the center still has a slight wobble when you nudge the dish.
- Rest 10 minutes before serving. Spoon it out warm, straight from the dish, scooping down through the crisp top to the soft custard underneath.
