Torta rogel
Birthdays in Buenos Aires are where the rogel shows off: eight or more wafer-thin, crackling discs of egg-yolk pastry, each spread with thick dulce de leche, stacked high and finished with a cloud of glossy Italian meringue browned with a blowtorch. Confiterías sell it by the slice, and it is a cake of contrasts, crisp and chewy, very sweet against the faintly salty pastry. It is laborious rather than difficult, and it slices best after a few hours' rest, when the dulce de leche has softened the layers just slightly. Use thick dulce de leche repostero (bakers' style); the runny kind for spreading on toast makes the tower slide. Rolling the discs too thick is the classic mistake: they should be so thin you can almost see the worktop through them, or the cake becomes heavy and hard to cut. Chef's tip: prick every disc all over with a fork before baking, or it puffs into a dome and won't stack flat.
