Quesillo — Venezuela's caramel custard with tiny holes

i. Origin & history

Caramel custards came to Latin America from Spain and Portugal, where flan and pudim were long established, themselves heirs to older European egg custards. Across the Spanish-speaking world, local versions developed, and in Venezuela the custard took a distinct form and name. Quesillo means 'little cheese', and the usual explanation is its appearance when cut: a cross-section dotted with small holes, like a fresh cheese such as Emmental, rather than the dense, glassy smoothness of a classic flan.

Modern quesillo is built on sweetened condensed milk, which became a pantry staple in Venezuela, as across Latin America, during the twentieth century. Condensed milk made the custard quicker, more reliable and richer, and today almost every Venezuelan family recipe uses it. Quesillo is made at home for birthdays, Christmas, Sunday lunches and family gatherings, and sold by the slice in bakeries (panaderías) and street stalls.

Venezuelans make it in a quesillera, a round metal mould with a clip-on lid, which is set in a pan of simmering water on the hob or in the oven. The lid keeps condensation off the custard and holds in steam. Many Venezuelans living abroad carry a quesillera with them, and it is often the first thing they look for when setting up a kitchen.

Quesillo is often compared with Mexican and Spanish flan and with Brazilian pudim de leite condensado, which is very similar. The main differences are technique and texture: quesillo is traditionally blended, uses whole eggs including the whites, and is cooked a little hotter, all of which produce its characteristic small holes and firmer slice.

ii. Where the holes come from

The holes in quesillo are not a mistake. They come from three things. First, the mixture is blended — often in an electric blender — which incorporates fine air bubbles. Second, quesillo uses whole eggs, and egg whites set into a firmer, springier structure than yolks alone, able to trap those bubbles. Third, it is cooked at a slightly higher heat than a silky flan, which expands the air and steam as the custard sets around them.

The result is a custard with a spongy, slightly airy texture and a firm slice. If you want a smoother quesillo with fewer holes, blend briefly, let the mixture rest for 15 minutes so the foam rises, skim it off, and bake at a gentler heat. If you want more holes, blend for longer.

The caramel is made directly in the mould. Sugar is melted and cooked until it turns a deep amber, then swirled over the base and sides. As the custard cooks, some of the caramel dissolves into a thin, bittersweet syrup that runs down the sides when the quesillo is turned out. A caramel that is too pale is merely sweet; one that goes too dark becomes bitter.

The water bath protects the custard. Eggs set gently between about 70 and 85 °C; above that, they overcook and become rubbery and weep liquid. Surrounding the mould with hot water keeps the temperature even and prevents the outside from overcooking before the centre has set.

• 150 g sugar, for the caramel
• 2 tbsp water, for the caramel
• 395 g sweetened condensed milk (1 tin)
• 350 ml whole milk (one condensed-milk tin's worth)
• 5 whole eggs
• 1 tsp vanilla extract
• 1 tbsp dark rum, optional
• ¼ tsp salt

Venezuelan cooks measure the milk with the empty condensed milk tin, which conveniently rinses it out. Whole eggs are essential: the whites give quesillo its firm, holey texture. Whole milk gives the right richness; evaporated milk makes a denser, creamier version, also popular. A splash of Venezuelan rum is traditional in many families. Without a quesillera, use a 20 cm round cake tin or 1 litre loaf tin covered tightly with foil.

iv. Method

1. Heat the oven to 180 °C (350 °F), or 160 °C fan, and boil a kettle.
2. Make the caramel: put the sugar and water in the quesillera or a 20 cm round tin and heat directly on the hob over a medium heat, swirling (not stirring), until it turns a deep amber, 5–7 minutes. Protect your hand with a cloth and tilt the mould to coat the base and a little way up the sides. Leave to set.
3. Blend the condensed milk, milk, eggs, vanilla, rum and salt for 30–60 seconds until smooth.
4. Pour the mixture over the hardened caramel. Close the lid of the quesillera, or cover the tin tightly with foil.
5. Set the mould in a deep roasting tin and pour in boiling water to come halfway up its sides. Bake for 50–60 minutes, until the custard is set at the edges with a slight wobble in the centre, and a knife inserted halfway between edge and centre comes out clean.
6. Lift out of the water bath, uncover and cool to room temperature, then refrigerate for at least 4 hours, ideally overnight.
7. To serve, run a thin knife around the edge, place a deep plate on top and invert in one quick movement. Lift off the mould and let the caramel run over the quesillo.

v. Tips & common mistakes

• Take the caramel to deep amber. Pale caramel tastes only of sugar. Stop just before it smokes; it continues to darken off the heat.
• Do not stir the caramel. Stirring encourages crystallisation. Swirl the pan instead.
• Blend to suit the texture you want. Longer blending gives more holes; a short blend and rest gives a smoother quesillo.
• Always use a water bath. Direct oven heat overcooks the custard, making it rubbery and weepy.
• Cover the mould. A lid or foil stops a skin forming and condensation dripping onto the custard.
• Chill before unmoulding. A warm quesillo is fragile and may crack. A night in the fridge sets it firmly and dissolves more caramel into syrup.

vi. Variations

Quesillo de piña adds pineapple juice or crushed pineapple. Quesillo de coco replaces part of the milk with coconut milk and adds grated coconut. Quesillo de chocolate blends in cocoa or melted chocolate. Quesillo de café adds strong coffee. Quesillo de auyama uses pumpkin purée, and quesillo de queso crema blends in cream cheese for a richer, cheesecake-like version.

Related custards include Brazil's coconut-yolk quindim, Turkey's caramelised milk pudding kazandibi, and from the same Iberian dessert tradition, Portugal's rice pudding arroz doce. For other Latin American milk sweets, see dulce de leche and Peru's suspiro limeño.

vii. Serving & storage

Serve quesillo cold, cut into wedges, with plenty of the caramel syrup spooned over each slice. In Venezuela it is the dessert at birthday parties, Christmas gatherings and Sunday lunches, and an everyday sweet at bakeries. Strong black coffee (un cafecito) is the usual accompaniment.

Covered in the fridge, it keeps for 3–4 days; the caramel continues to dissolve into a syrup. It does not freeze well, as the custard becomes watery and grainy when thawed.
