Ingredients
Method
- Preheat oven to 175°C (155°C fan / Gas 3½). Line a 20cm square tin.
- Melt the chocolate and butter together and cool for 10 minutes.
- Whisk the eggs, yolks, sugars and vanilla for 3–4 minutes until thick and glossy.
- Fold in the melted chocolate mixture.
- Sift in the flour, cocoa and salt and fold gently.
- Pour into the tin, sprinkle with sea salt and bake for 22–25 minutes until the middle is still slightly soft.
- Cool for 1 hour, then chill for at least 2 hours.
- Cut into squares with a hot knife.
Notes
Underbake slightly and chill to get a truly fudgy texture.
Extra yolks and less flour give the densest result.
Whisk the eggs and sugar well for a shiny crust.
Cut with a hot, clean knife.
Freeze cut squares for up to 3 months.
