Method
- Bake at 170 C for 22–30 min until the centre is 88–92 C and wobbles slightly.
- Cool for at least 2 h, then slice with a warm clean knife.
Principles
- Protein coagulation — Heat sets egg proteins for structure.
- Sugar film formation — Dissolved sugar forms the crackled surface.
- Starch gelatinisation — Flour starch helps set the cooled matrix.
