Boniatillo

Sweet potato pudding

Boniatillo: Cuban sweet-potato pudding with lime and cinnamon

Boniatillo comes from the sweet tooth of old Havana, where white-fleshed boniato is boiled, puréed and cooked in a cinnamon and lime-peel syrup until it turns into a thick, glossy pudding. It is served at room temperature in small bowls, often dusted with cinnamon, at birthdays or simply after Sunday lunch. The mistake to avoid is using orange sweet potato alone, which makes it wet and very sweet; Cuban boniato or a white sweet potato gives the right dry, chestnutty texture. Chef's tip: beat in the egg yolks off the heat with a little of the hot purée first, so they thicken the pudding without scrambling.

Method

0/5 done
  1. Step 1: Boil 1 ½ lb white sweet potato (boniato) in plenty of water for 15–20 minutes, until very tender. Drain well and mash until completely smooth.

    20 min
  2. Step 2: In a wide pan, simmer 7 oz sugar, ¾ cup water, 1 cinnamon stick and 2 strips lime peel for 8 minutes, until slightly syrupy. Remove the cinnamon and peel.

    8 min
  3. Step 3: Add the mashed boniato and 1 pinch salt to the syrup and cook over a low heat, stirring constantly with a wooden spoon, for 12–15 minutes, until thick enough that the spoon leaves a trail across the pan base.

    15 min
  4. Step 4: Off the heat, beat 2 egg yolks with 2 spoonfuls of the hot purée, then stir them back in with ⅔ oz butter and 1 tsp vanilla extract. Return to a low heat for 2 minutes, stirring, to cook the yolks.

    2 min
  5. Step 5: Spoon into small bowls, cool to room temperature and dust with ½ tsp ground cinnamon. Keeps 3 days in the fridge; bring back to room temperature before serving.

Kartoshka cakeCocoa and cake crumb truffles

Soviet cafés and school canteens sold these knobbly brown 'potatoes' for a few kopecks, and they began as a thrifty way to use up sponge and biscuit trimmings at the bakery. Crumbs are bound with butter and sweetened condensed milk, flavoured with cocoa and vanilla, shaped into little potatoes, rolled in cocoa and finished with two dabs of pale butter cream for the sprouts. They are fudgy and dense like a brownie truffle, need no oven, and children love making them. Traditional bakers added a spoonful of rum, an optional extra for adult batches only; this version is alcohol-free with vanilla. The usual slip is coarse crumbs, which make the potatoes crack, so blitz them as fine as sand. Chef's tip: chill the shaped potatoes for at least 20 minutes so they hold their shape and slice cleanly.

Undu walaluFried urad dal rings in treacle

Walalu means bangles, and these dark, sticky rings of fried urad dal soaked in kithul treacle are a sweet that Sinhala families bring out for Avurudu and for special almsgivings, often made in large batches by an aunt known for her steady hand. A thick, fluffy paste of ground black gram is piped into loops and fried until crisp, then plunged straight into warm treacle, so the rings stay crunchy on the outside while drinking up the syrup. They taste a little like a darker, smokier jalebi, with a toffee finish from the palm treacle. Watery batter is what ruins them; it spreads into flat blobs, so grind the soaked dal with as little water as possible and beat it until light. This recipe uses no asafoetida, so it is naturally gluten free. Chef's tip: pipe the rings onto small squares of baking paper and lower them into the oil paper and all; the paper peels away in seconds.

Crema de malangaMalanga root soup

Ask anyone raised in Havana what they were fed when they were ill and the answer is usually crema de malanga: a pale, velvety soup of the starchy root, gently scented with garlic and onion. It is also one of the first foods Cuban babies and grandparents alike are given, because it is soft, mild and filling. The classic mistake is grating raw malanga with bare hands, which can make your skin itch; peel it wearing gloves and rinse it well. Serve it plain or with a few croutons. Chef's tip: blend in the butter at the end rather than frying in it, so the soup tastes clean and creamy rather than heavy.
