Walnut Cake with Salted Caramel

Line the bottom of a ∅ 24 cm cake tin with baking paper and grease the sides with butter and dust with coarse flour.

Sift the flour together with the sugar and stir in the salt.

Whisk the eggs in a bowl with a whisk, gradually pouring in the oil while continuously whisking, until a mixture slightly resembling mayonnaise forms. Then whisk in the buttermilk and mix in the dry ingredients.
