Rhubarb & Caramelised White Chocolate Choux Nuts

Pastry

Crisp choux pastry, sharp roast rhubarb with a hint of vanilla, and butterscotch-sweet caramelised white chocolate cream; a delicious combination you’ve got to try, and a great way to celebrate seasonal British produce (and millennial pink… *sigh*).

Ingredients (makes 10-12)

For the choux

  • 85g unsalted butter
  • 220ml water
  • 100g plain flour
  • 3 eggs
  • pinch of salt

For the filling

  • 250g white chocolate (make sure it’s at least 30% cacao)
  • 300ml double cream
  • Pinch salt
  • 4 thick stems rhubarb
  • 3tbsp caster sugar
  • 2 vanilla pods or 1tsp vanilla extract
  • Juice and zest 1 lemon

For the topping

  • 100g icing sugar
  • Enough of the rhubarb syrup (leftover from roasting the rhubarb) to create an icing with a drizzle-consistency
  • Dried rose petals (optional)
  • Candied rhubarb ribbons (optional) (I make these by creating ribbons of rhubarb with a peeler, which I then simmer in a simple 2 parts sugar: 1 part water syrup for 5 minutes before draining off any excess liquid and cooking at 160c for 10-15 minutes, or until dried out, on a lined baking tray)

Method

  1. To make the choux put the water, butter and salt in a saucepan set over a medium heat (do not let it boil at this stage). Meanwhile, sieve the flour to remove any lumps. When the butter has melted into the water, increase the heat and bring to a rolling boil, then tip in the flour and stir vigorously until you have a smooth paste-like mix which comes away from the edges of the pan. Continue to stir for another minute to cook out the rawness of the flour, then tip into a clean bowl and close cover with cling film (this eggless stage is known as a ‘panade’). Leave to cool to room temperature.
  2. Preheat the oven to 190c. Line 2 large baking trays with greaseproof paper.
  3. Once the panade has cooled it’s time to add the eggs; whisk in a jug to break them up then very gradually add into the panade while beating with electric beaters. Stop adding the egg (you might have a little leftover) when the smooth, lump-free mixture reluctantly drops off the end of a spoon. Pile the choux mix into a piping bag, fitted with a large round nozzle.
  4. Pipe 10-12 doughnut shapes onto the prepared baking trays, leaving room for expansion. Bake the choux for 20-25 minutes or until crisp and golden, then skewer each one and return to the oven for around 10 minutes or until the middles have completely dried out. Set aside to cool and reduce the oven temperature to 180c.
  5. Slice the rhubarb into batons and toss in the caster sugar, lemon juice and zest and vanilla. Roast for 10-15 minutes in a high sided baking tray until the pieces are tender but still retain their shape. Set aside to cool and reduce the oven temperature to 120c.
  6. Chop up the white chocolate and scatter on a lined baking tray in an even layer. Place in the oven to allow the chocolate to melt for 10 minutes, then stir/turn and return to the oven for another 10 minutes. Repeat this step 2-3 more times until the chocolate reaches a deep golden colour, then scrape into a bowl and mix in a splash of cream to loosen the consistency (it can get a little grainy at this stage so pass through a sieve if necessary). Leave to cool.
  7. Once the white chocolate has cooled, place in a bowl (or bowl of a stand mixer with whisk attachment) and add in the cream and salt. Whisk until pipe-able.
  8. Slice the cooled choux nuts in half horizontally and pipe in a generous helping of caramelised white chocolate cream. Slice the roast rhubarb pieces thinly and arrange these on top of the cream, then pop the choux lid on top.
  9. For the pink icing, pour the cooking syrup from the rhubarb tray into the icing sugar and mix to create a smooth drizzle-like consistency (add in a little water if you don’t have enough syrup). Spoon this over the filled choux-nuts and garnish with edible petals and rhubarb ribbons.
Enjoy!
