In a medium bowl, beat the egg whites with the cream of tartar until soft peaks form. Gradually add half of the sugar (50 g) and beat until stiff peaks form.

In a separate bowl, beat the egg yolks with the remaining sugar and vanilla extract until light and fluffy.

Gently fold the egg yolk mixture into the egg whites. Sift the flour and salt over the mixture and gently fold until combined.

Spread the batter evenly onto the prepared baking sheet. Bake for 12-15 minutes, or until lightly golden and the cake springs back when touched.

Whisk the heavy whipping cream and powdered sugar until stiff peaks form. Gently fold in the melted white chocolate and raspberry jam.
