Yolks only, and why the oven is barely on

Egg yolk sets around 65 to 70°C, white nearer 62°C but far more tightly — whites give you a rubbery, weeping custard, so this uses none. Yolks also carry lecithin, which emulsifies the fat in the cream and keeps the set silky rather than curdled. Even so, the margin between set and split is narrow, so the oven sits at 130°C and the custard coasts gently up to temperature. It should still be trembling when you take it out, because carryover heat finishes it.

Notes

  • Nine yolks is not a misprint. Fewer and the tart will not hold a clean edge.
  • Strain the custard. It removes chalazae and any strand of set egg.
  • Trim the pastry overhang with a serrated knife after baking, flush with the tin.

Try butter, 30 minutes, braise, or an ingredient you need to use up.
