The method
- 01
Butter and cocoa-dust four ramekins right into the corners, then chill them.
- 02
Melt chocolate and butter together over barely simmering water; cool slightly.
- 03
Whisk eggs, yolks and sugar to a pale ribbon, then fold in the chocolate and finally the flour.
- 04
Fill the ramekins ¾ full and rest in the fridge at least 30 minutes (up to a day).
- 05
Bake at 425°F for 11–12 minutes: set edges, wobbling centre. Rest one minute, invert, dust, serve immediately.
