ABOUT THIS RECIPEA crumb that holds the syrup
Baba au rhum is not an ordinary cake made with baking powder, but a small yeast cake. The dough contains eggs and butter, which makes it soft and sticky; after rising and baking, it develops an open, springy crumb. Those little holes matter: they soak up syrup without the cake immediately becoming heavy or dense. Use metal baba or savarin moulds, or a muffin tin with roomy cups. Grease them carefully so the risen cakes come out of the moulds in one piece after baking.
Give the dough time to rise. The first rise builds flavour and structure; after dividing it among the moulds, it needs a second rise. The exact time depends on the temperature in the kitchen, so pay attention to the volume: the dough should become visibly airy and rise almost to the rim of the moulds. The butter is gradually mixed into the dough, not melted beforehand. This keeps the dough supple and lets the crumb expand into an airy texture later. A stand mixer with a dough hook is handy, but you can also do it by hand with a sturdy spoon and a little patience.
The syrup should taste sweet and distinctly of rum; the cakes themselves are only lightly sweetened. Take the pan off the heat before adding the rum, so its aroma is preserved and the alcohol does not evaporate any further than necessary. Use a rum you enjoy drinking. Dark rum gives a fuller aroma, while a lighter rum is more subtle. Let the baked cakes cool first, then dip them in warm syrup. Turn them carefully and give them time to soak up the liquid, but don’t leave them so long that they fall apart.
Orange segments bring juiciness and a lightly bitter, fresh note alongside the rum; citrus is widely available, especially in the colder months, but this dessert can be served all year round. Cut out the segments without the white pith for a softer texture. The whipped cream is left unsweetened so the syrup doesn’t taste even sweeter. You can make the cakes and syrup ahead of time and soak the baba a few hours before serving. Store soaked cakes covered in the refrigerator and serve them chilled or at room temperature; keep the whipped cream chilled separately and whip it shortly before serving.
