Preheat oven to 350°F (175°C). Grease and line a 9-inch round pan with parchment paper.

In a large bowl, beat eggs and sugar on high for 8–10 minutes until thick, pale, and tripled in volume.

Sift flour over the mixture in 3 parts, folding gently after each addition to maintain volume.

Pour batter into pan and bake 30–40 minutes, until golden and springy.

Cool in pan 10–15 minutes, then invert onto wire rack to cool fully.

Slice and serve as-is or with fruit and cream.
