Tocino del cielo is a rich, dense Spanish dessert made primarily from egg yolks and sugar syrup, baked into a caramel-lined mold and served in slices. Its name means “bacon from heaven,” a nod to its golden color and luxurious texture. This recipe works because the slow, gentle baking sets the custard into a silky, flan-like slice with a deeply caramelized flavor.
Ingredients
- 2 cups (400 g) granulated sugar, divided
- 1/2 cup (120 ml) water
- 12 large egg yolks (about 3/4 cup / 180 ml)
- 1 teaspoon vanilla extract (optional)
- Pinch of salt
Instructions
- Preheat your oven to 325°F (163°C). Have ready an 8-inch round cake pan or a 9-inch pie dish, plus a larger roasting pan for the water bath.
- Make the caramel: In a small saucepan, combine 1 cup (200 g) of the sugar with the water. Stir gently over medium heat until the sugar dissolves, then stop stirring. Bring to a boil and cook until the syrup turns a deep amber color, about 8–10 minutes. Watch closely—caramel can burn quickly.
- Immediately pour the hot caramel into the cake pan, tilting to coat the bottom evenly. Set aside to cool and harden while you prepare the custard.
- In a large bowl, whisk the egg yolks with the remaining 1 cup (200 g) sugar, vanilla, and salt until well combined and slightly thickened. Do not over-whisk, as you don’t want to incorporate too much air.
- Gradually pour the warm (not boiling) sugar syrup from the caramel-making step into the yolk mixture? Actually, you already used all the sugar for caramel. Instead, heat 1/2 cup (120 ml) water with the remaining 1 cup (200 g) sugar in a small saucepan until the sugar dissolves and the syrup is hot but not boiling. Slowly drizzle this hot syrup into the yolks while whisking constantly to temper them. Continue whisking until smooth.
- Strain the custard through a fine-mesh sieve into a measuring cup or directly into the caramel-lined pan. This removes any cooked bits and ensures a silky texture.
- Place the cake pan into the roasting pan. Pour hot water into the roasting pan until it reaches halfway up the sides of the cake pan. This water bath (bain-marie) prevents the custard from curdling.
- Bake for 45–55 minutes, until the custard is set around the edges but still slightly jiggly in the center. The internal temperature should read 160°F (71°C) on an instant-read thermometer, which is the USDA FSIS safe minimum for egg dishes.
- Remove the pan from the water bath and let it cool to room temperature on a wire rack. Then cover and refrigerate for at least 4 hours, preferably overnight, until fully chilled and firm.
- To unmold, run a thin knife around the edge of the pan. Place a serving plate upside down over the pan, then quickly invert both. The caramel will flow over the custard as a sauce. Slice and serve chilled.
Tips
- Caramel watch: The caramel goes from golden to burnt quickly. Remove it from heat when it’s a deep amber, like the color of a copper penny. If it darkens too much, it will taste bitter.
- Egg yolks: Use fresh, high-quality eggs. The yolks should be bright orange for the classic color. Leftover egg whites can be used for meringues or omelets.
- Water bath: Don’t skip the water bath—it ensures gentle, even heat. Make sure the water is hot but not boiling when you add it to the roasting pan.
- Straining: Always strain the custard before baking. It removes any bits of coagulated yolk and gives a perfectly smooth texture.
Serving Suggestions
Serve tocino del cielo chilled, cut into wedges like a cake, with the caramel sauce spooned over each piece. It pairs beautifully with a small dollop of lightly sweetened whipped cream or a few fresh berries to cut the sweetness. A cup of strong Spanish coffee or a glass of Pedro Ximénez sherry makes an excellent accompaniment.
Variations
- Citrus twist: Add the zest of one lemon or orange to the custard before baking for a bright, aromatic note.
- Spiced version: Infuse the sugar syrup with a cinnamon stick or a star anise while heating, then remove before mixing with the yolks.
- Individual servings: Instead of one large pan, use 6–8 ramekins. Reduce the baking time to 25–30 minutes, and check for doneness at 25 minutes.
- Reduced sugar: If you prefer less sweetness, reduce the sugar in the custard to 3/4 cup (150 g), but keep the caramel as is. The texture will be slightly softer.
Storage and Reheating
Store tocino del cielo in the refrigerator, covered, for up to 4 days. Keep it in the pan with the caramel sauce, or unmold and store in an airtight container. It is best served cold, so there is no need to reheat. If you’ve unmolded it, the caramel sauce may thicken upon refrigeration; let it sit at room temperature for 10 minutes before serving so the sauce flows again. You can also freeze it for up to 1 month, wrapped tightly in plastic wrap and foil. Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Can I use whole eggs instead of just yolks? No, the recipe relies on the high yolk-to-liquid ratio to achieve its dense, creamy texture. Using whole eggs would make it more like a regular flan and less rich.
Why did my caramel harden and stick to the pan? That’s normal—caramel hardens as it cools. The water bath and the moisture from the custard will dissolve it during baking, creating a sauce. Make sure you pour the caramel into the pan while it’s still liquid.
Can I make this without a water bath? You can, but the texture will be less creamy and more likely to curdle. The water bath is essential for even cooking. If you must skip it, bake at 300°F (149°C) and check for doneness earlier.
How do I know when it’s done? The edges should look set, but the center should still wobble slightly when you shake the pan. A thermometer should read 160°F (71°C). It will finish setting as it cools.
Can I use a different size pan? Yes, but adjust the baking time. A wider, shallower pan will bake faster; a deeper pan will take longer. Keep an eye on it and use the thermometer as your guide.
Why is my tocino del cielo grainy? Graininess usually comes from overcooking or from the sugar not being fully dissolved. Make sure your syrup is completely dissolved before adding to the yolks, and don’t overbake.
