Grease a 33 x 23cm/13 x 9in Swiss roll tin and line with baking paper. In a large mixing bowl, whisk the eggs and sugar together on high speed for about 5 minutes until very pale, thick and fluffy. The beaters will leave a ribbon-like trail of mixture when lifted from the bowl.Sift the flour over the mixture and gently fold in using a large metal spoon. Pour the mixture into the prepared tin and use a spatula to spread it evenly into the corners. Bake for 8–10 minutes, until lightly golden and firm to the touch. While the sponge is baking, cut a rectangle of baking paper slightly larger than the Swiss roll tin. Lay it on a work surface and sprinkle with 2 tablespoons of caster sugar. Turn the sponge out onto the sugar-dusted paper, then carefully peel off the baking paper. Cool the sponge in the fridge for 10 minutes.Whisk the cream to soft peaks. Spread it evenly over the cooled sponge, leaving a 2.5cm/1in border at one of the shorter ends. Dot the jam over the cream and swirl it through to make a ripple pattern. Starting at a short end, roll up the sponge, finishing at the end with less cream. Transfer the Swiss roll to a serving plate. Sprinkle with a further 1 tablespoon of caster sugar.
