Rhubarb Creme Brulee: A Symphony of Tart and Sweet

The arrival of spring always brings a rush of anticipation to my kitchen, a craving for the season’s first vibrant offerings. And nothing embodies that fresh, rosy promise quite like rhubarb. I remember the first time I encountered rhubarb creme brulee – it was a revelation. The classic, silken custard, with its shatteringly crisp caramelized sugar top, was transformed by a hidden layer of bright, tangy rhubarb puree. It was a dessert that whispered of sunshine and renewal, a perfect counterpoint to the rich, comforting flavors of winter. This twist on a French classic is truly sensational, a delightful welcome to warmer days.

Equipment Needed

Instructions

The magic of this Rhubarb Creme Brulee lies in its two distinct components, each requiring a little love and attention to reach perfection.

Preparing the Rhubarb Purée

1. Begin by preparing the vibrant rhubarb base. In a small saucepan, combine the chopped rhubarb, granulated sugar, light brown sugar, and water.
2. Bring the mixture to a boil over medium heat. Once boiling, reduce the heat to a gentle simmer.
3. Continue to simmer for approximately 10 minutes, stirring occasionally. The goal is for the rhubarb to soften and the mixture to thicken slightly. You’ll know it’s ready when the rhubarb pieces are tender and have broken down into a luscious purée.
4. Once cooked, let the rhubarb mixture cool completely. This cooling period is crucial for allowing the flavors to meld and for the purée to reach the right consistency.

Crafting the Custard

1. Now, let’s turn our attention to the velvety smooth custard. In a medium saucepan, gently heat the whipping cream until it’s almost simmering. You want it to be hot to the touch, but not boiling. This process is called tempering and helps to ensure the eggs don’t scramble when they’re added.
2. While the cream is heating, in a mixing bowl, whisk together the egg yolks, whole eggs, and granulated sugar. Stir these ingredients together just until blended. The mixture should be smooth and homogenous.
3. With a slow, steady stream, gradually stir the hot cream into the egg mixture. This is a critical step: pour the cream in a thin, constant stream while continuously whisking the eggs. This gentle process gradually raises the temperature of the eggs, preventing them from cooking too quickly.
4. Once all the cream has been incorporated, strain the custard mixture through a fine-mesh sieve into a heatproof bowl or a large measuring cup. This step is essential for achieving an ultra-smooth, silken texture by removing any chalazae (the stringy bits in egg yolks) or any small cooked egg bits.
5. Stir in the vanilla extract into the strained custard.

Assembling and Baking

1. Divide the cooled rhubarb purée evenly among six ramekins or custard cups. Aim for a consistent layer at the bottom of each.
2. Carefully spoon the custard mixture over the rhubarb purée in each ramekin. Fill them almost to the brim, leaving just a little space at the top.
3. Now, prepare for the water bath. Place the filled ramekins into a large roasting pan, ensuring they don’t touch each other. This pan needs to be large enough to hold them all comfortably.
4. Pour in enough hot tap water into the roasting pan to come halfway up the sides of the custard cups. This water bath, also known as a bain-marie, provides gentle, even heat, preventing the custards from cracking and ensuring a silky-smooth texture.
5. Carefully place the roasting pan into a preheated oven set at 300°F (150°C).
6. Bake for approximately 1 hour. The custards are ready when they are set around the edges but still quiver gently in the center when the pan is gently shaken. Be mindful that oven temperatures can vary, so keep an eye on them towards the end of the baking time.

Chilling and Finishing

1. Once baked, carefully remove the ramekins from the water bath. They will be quite hot, so use tongs or oven mitts.
2. Let the custards cool to room temperature. This allows them to continue setting and begin to firm up.
3. Once at room temperature, cover each ramekin tightly with plastic wrap. This prevents a skin from forming on the surface.
4. Refrigerate the custards for at least 6 hours, or preferably overnight, up to 2 days. This extended chilling time is crucial for the custards to fully set and develop their characteristic rich, creamy texture.

Serving Your Rhubarb Creme Brulee

1. Just before serving, gently blot any liquid that may have formed on the surface of the custards with paper towels. This ensures a clean surface for caramelization.
2. Sprinkle 2 teaspoons of the remaining light brown sugar evenly over the top of each custard. Ensure a uniform layer for even caramelization.
3. Transfer the ramekins to a baking sheet. This makes it easier to move them under the broiler or to use your kitchen torch.
4. Broil as close as possible to the heat source, watching them very carefully. The sugar should melt and caramelize in approximately 2 minutes. Alternatively, use a kitchen torch, moving it constantly over the sugar until it turns a beautiful amber color. The key here is vigilance – sugar can burn very quickly!
5. Let stand until the sugar hardens into a glorious, crisp crust. This typically takes a few minutes.
6. Desserts may be refrigerated for up to 1 hour after broiling, but the caramelized sugar is best enjoyed fresh.

Expert Tips & Tricks

• Room Temperature Ingredients: While not explicitly stated for the custard itself, using room temperature eggs and cream can help them emulsify more smoothly. However, the heating of the cream addresses this for the custard.
• Don’t Overmix the Custard: Once you’ve blended the eggs and sugar, resist the urge to over-whisk. Overmixing can incorporate too much air, leading to a less smooth final texture.
• Water Bath is Key: Never skip the water bath. It’s the secret to custardy perfection, ensuring that gentle, even cooking that prevents curdling and yields that signature silky texture.
• Testing for Doneness: The “gentle quiver” test is your best friend. If the custard is completely rigid, it’s likely overbaked. A slight wobble is exactly what you’re aiming for.
• The Perfect Caramel Crust: The thickness of your brown sugar layer will affect how quickly it caramelizes. Experiment to find what works best for your broiler or torch. A thin, even layer is usually ideal.

Serving & Storage Suggestions

Serve this exquisite Rhubarb Creme Brulee immediately after the sugar crust has hardened. The contrast between the warm, crisp caramel and the cool, creamy custard with its tart rhubarb surprise is simply divine.

For storage, the un-torched custards can be kept tightly covered in the refrigerator for up to 2 days. However, the magic of creme brulee truly lies in that freshly torched sugar crust. If you’ve torched them ahead of time, they can be refrigerated for up to an hour, but the crust may soften over time.

Variations & Substitutions

While this recipe is a classic for a reason, feel free to play with the rhubarb element. If rhubarb is out of season, a vibrant berry purée, like raspberry or strawberry, could offer a similar tart and sweet profile. A hint of ginger or a touch of orange zest added to the rhubarb purée could also offer an interesting aromatic dimension.

FAQs

Q: Why is my custard watery after refrigerating?
A: This can happen if the custard was overbaked or if it wasn’t chilled long enough. Ensure it’s set but still quivering before removing from the water bath and chill for the full recommended time.

Q: Can I make the rhubarb purée and custard ahead of time?
A: Yes! The rhubarb purée and the unbaked custard can be made a day in advance and stored separately in the refrigerator. Assemble and bake the day you plan to serve, or bake and chill, then torch just before serving.

Q: My sugar isn’t caramelizing properly. What am I doing wrong?
A: Ensure your broiler is on high and positioned close to the custards, or that your torch is held at the correct distance. Also, make sure the brown sugar layer is relatively even and not too thick.

Q: Can I use different types of sugar for the caramel topping?
A: While light brown sugar is traditional and provides a lovely color and flavor, you can experiment with granulated sugar. However, brown sugar’s molasses content aids in a more even and slightly softer caramelization.

Q: What if I don’t have a kitchen torch or a broiler?
A: Unfortunately, the signature crisp sugar crust of creme brulee is best achieved with a torch or broiler. Alternative methods may not yield the same satisfying crunch.
