Baba au Rhum — a light yeast cake drenched in rum syrup

i. Origin & history

The baba's story begins with Stanisław Leszczyński, the deposed King of Poland who became Duke of Lorraine in eastern France in the 1730s. The legend most often told is that he found the local kugelhopf too dry and had it moistened with sweet wine, and that the result was named "baba" — a Polish word for an old woman or grandmother, and the root of the babka, a tall Polish yeast cake. A later and more colourful version claims he named it after Ali Baba from the Thousand and One Nights. Neither account can be proved, but the link to Stanisław and Lorraine is consistent.

Stanisław's daughter Marie married Louis XV, and her pastry cook, Nicolas Stohrer, is said to have brought the baba to Versailles and then to Paris, where he opened his pâtisserie on the rue Montorgueil in 1730. Stohrer still trades on the same street and remains closely associated with the baba. Early versions were soaked in wines such as Malaga or Tokaji; rum, which became widely available in France through Caribbean trade, took over in the nineteenth century and gave the cake its modern name.

In the 1840s the Parisian pâtissiers the Julien brothers developed the savarin, a baba dough baked in a ring mould, without raisins, soaked in syrup and filled with cream or fruit; they named it after the gastronome Jean Anthelme Brillat-Savarin. Babas and savarins became standard items in French pastry shops.

The baba also travelled to Naples, probably with French chefs employed by the city's aristocracy in the nineteenth century, and the babà became one of the most beloved Neapolitan pastries, often sold in a tall mushroom shape and eaten in the street, alongside the sfogliatelle.

ii. Why a baba must be dry before it is soaked

A baba is designed to be a sponge. The dough is very soft and wet — closer to a thick batter than a bread dough — and rich with eggs and butter. Beaten hard, it develops a stretchy gluten network, and the yeast fills it with gas. Baked, it becomes a light, open-crumbed cake with a strong structure of interconnected air pockets, perfect for absorbing liquid.

The key is that the baked cake must be dry. A fresh, moist baba absorbs little syrup and can collapse into a soggy mass when soaked. Pastry chefs bake babas a day ahead and leave them uncovered to dry and go slightly stale, or return them to a low oven to dry further. A dry baba drinks up syrup evenly all the way to the centre, roughly doubling in weight while keeping its shape.

Temperature makes soaking work. The usual rule is a contrast: dry, cool babas go into warm syrup (around 50–60 °C), or warm babas into cooler syrup. Warm syrup is less viscous and penetrates the crumb faster; if both cake and syrup are hot, the cake can become too soft and fall apart, and if both are cold, the syrup barely soaks in.

The rum is added to the syrup after it has been taken off the heat, or brushed onto the soaked babas at the end, so that its aroma is not lost to evaporation. A final glaze of warm apricot jam seals in moisture and gives the classic shine.

• 250 g strong white flour
• 7 g instant yeast
• 20 g caster sugar
• ¾ tsp fine salt
• 4 large eggs, at room temperature
• 50 ml whole milk, lukewarm
• 80 g unsalted butter, soft, plus extra for the moulds
• 500 ml water
• 250 g caster sugar, for the syrup
• 1 orange, peel in wide strips
• 1 lemon, peel in wide strips
• 1 vanilla pod, split
• 120 ml dark rum, plus extra to serve
• 3 tbsp apricot jam, warmed and sieved
• 300 ml double cream
• 1 tbsp icing sugar

Strong white flour gives the elastic gluten the dough needs to hold its shape; plain flour gives a weaker, more cake-like baba. Use a good dark rum — Caribbean rhum agricole or an aged dark rum gives the best flavour, and since it is not cooked, its quality shows. For a less boozy baba, use half the rum in the syrup and offer more at the table. Traditional moulds are small fluted baba or dariole moulds; a muffin tin works, or bake the whole dough in a 22 cm buttered ring mould for a savarin. Some traditional recipes add a handful of rum-soaked raisins to the dough.

iv. Method

1. In a stand mixer with the dough hook, mix the flour, yeast, sugar and salt. Add the eggs and milk and beat on medium speed for 8–10 minutes until the dough is very smooth, elastic and pulls away from the sides of the bowl in sheets.
2. Add the soft butter a little at a time and beat for another 3–4 minutes until fully incorporated and glossy. Cover and leave in a warm place for about 1 hour, until doubled.
3. Generously butter eight 125 ml baba or dariole moulds. Knock back the dough and divide it between the moulds, filling them a third full. Cover loosely and prove for 30–45 minutes, until the dough rises just above the rims.
4. Heat the oven to 190 °C (375 °F), fan 170 °C. Bake on a tray for 18–22 minutes, until deep golden and hollow-sounding. Turn out onto a rack. Ideally leave uncovered for several hours or overnight to dry, or dry in a 120 °C (250 °F) oven for 15 minutes.
5. For the syrup, bring the water, sugar, citrus peel and vanilla to the boil, simmer for 5 minutes, then remove from the heat and leave until about 55 °C — hot but comfortable to touch. Stir in the rum.
6. Lower the babas into the warm syrup a few at a time, turning them with a slotted spoon and pressing gently, for 1–2 minutes, until saturated and heavy. Lift onto a rack set over a tray to drain.
7. Brush the babas with warm apricot jam. Whip the cream with the icing sugar to soft peaks. Serve each baba with cream and a little extra rum poured over at the table if liked.

v. Tips & common mistakes

• Beat the dough thoroughly. The long beating builds the gluten that gives the baba its springy, open structure. A short-mixed dough bakes dense and collapses in syrup.
• Bake until truly golden. Pale babas are underbaked inside and turn mushy when soaked.
• Dry them before soaking. Day-old, slightly stale babas absorb syrup evenly without falling apart.
• Mind the temperature contrast. Cool babas, warm syrup. Hot babas in hot syrup disintegrate.
• Add the rum off the heat. Boiling the syrup with the rum drives off its aroma.
• Soak generously. A properly soaked baba should be heavy and dripping; a dry centre is the most common disappointment.

vi. Variations

The savarin is baba dough baked in a ring, soaked in syrup and filled with Chantilly cream, pastry cream or fresh fruit. The Neapolitan babà is often larger and mushroom-shaped, sometimes split and filled with pastry cream or wild strawberries, and sold in rum or limoncello versions. Some French pastry shops serve babas split with a jar of rum on the side so diners can douse their own. A baba with raisins, closer to the original Lorraine cake, folds rum-soaked raisins into the dough.

Related enriched yeast cakes include the Polish babka, the Swedish semla and the German Bienenstich. For other cakes soaked in syrup, see the Middle Eastern basbousa and the Greek revani, and for the Neapolitan pastry tradition, sfogliatelle.

vii. Serving & storage

Serve babas at room temperature or slightly chilled, in a shallow bowl so they can sit in a little syrup, with softly whipped cream or Chantilly and perhaps some fresh berries or sliced oranges. A glass of the same rum alongside is traditional in some French brasseries. They are a classic bistro dessert and an elegant finish to a winter dinner.

Unsoaked babas keep for 2 days in an airtight container and freeze well for up to 2 months — in fact, slightly stale babas are better for soaking. Soaked and glazed babas keep, covered, in the fridge for up to 2 days; bring them to room temperature before serving. The syrup can be made several days ahead and refrigerated; warm it before soaking.
