Mango, white chocolate and makrut lime leaf cream éclairs

Instructions

1. Step 1

   To make the lime leaf syrup, slowly bring the sugar, water and lime leaves to the boil then set aside to infuse – for a few hours, if possible. After this time, remove the lime leaves

2. Step 2

   Preheat the oven to 200ºC/180°C fan/gas mark 6 and line two large baking trays with greaseproof paper. Draw 12 roughly 10cm long lines on the paper to use as guidelines

3. Step 3

   For the choux pastry, combine the water, butter and salt in a saucepan. Gently melt the butter over a low heat without bringing the mixture to the boil (you want the butter to be just melted, and avoid evaporating too much of the water)

4. Step 4

   Once the butter has melted, bring the mixture up to the boil and tip all the flour into the pan in one go. Remove the pastry from the heat

5. Step 5

   Use a wooden spoon to beat the mixture as fast as you can, bringing it all together into a dough that pulls away from the sides of the pan

6. Step 6

   Once the dough starts to pull away, return the choux pastry to the heat and continue cooking and stirring the dough (no need to beat it as frantically at this stage) until an instant read thermometer reads 74°C. A little above this temp is fine as well. If you don’t have a thermometer, continue cooking the dough until the base of the saucepan is covered in a fine film of pastry

7. Step 7

   Remove the dough from the pan and transfer it to the bowl of a stand mixer with a paddle attachment (or another bowl if using a wooden spoon) to cool a little. It helps to spread the dough out at this stage to cool it faster

8. Step 8

   Once the dough reaches 63°C or cooler, it’s time to add the eggs. Lightly beat the eggs together in a jug

9. Step 9

   Mix the dough on low speed, and gradually beat the eggs into the dough, ensuring each addition is fully incorporated before adding the next. It’s unlikely that you will need all of the egg. Keep adding egg until you have a mixture that reluctantly drops from the paddle, leaving a V shape. Another way to test if the dough is ready is by scooping some up onto a spoon then counting slowly to 6 - it should have dropped by the time you reach 6 (slow) seconds

10. Step 10

    Dab a few dots of the mixture in each corner of the baking trays to stick the greaseproof paper to the surface of the baking trays

11. Step 11

    Fit a piping bag with a star nozzle that’s around 1.25cm wide (with a lot of teeth, if possible). Fill the piping bag with the choux pastry

12. Step 12

    Place the filled piping bag onto a flat surface and carefully flatten the pastry mixture inside, taking care not to squeeze it out of the bag. Using a pastry scraper or other thin, flat object, gently push the choux pastry down into the bag to remove air bubbles and collect all the dough in one place. Twist the bag at the top and pipe a little of the mixture to remove any air bubbles near the tip

13. Step 13

    Carefully pipe the pastry over the guidelines on the baking paper at a 45 degree angle, if possible. Try to achieve a very slight ‘dog bone’ shape with the pastry, as this will ensure they are more evenly shaped once baked. It’s also important to try to pipe fairly slowly, otherwise the éclairs will be too skinny

14. Step 14

    Sprinkle a few drops of water around the éclairs (not touching the pastry) and transfer to the oven to bake for 25 minutes. After 25 minutes, swap the trays around for a further 5 minutes, or until the pastry is deep golden brown and crisp – they should sound hollow when tapped

15. Step 15

    Prick the underside of the éclair shells with a cocktail stick and transfer onto a wire rack to cool completely

16. Step 16

    To make the lime leaf cream, whisk the cream, sugar and 2 tbsp of the lime leaf syrup together until soft peaks form, then refrigerate until needed (no more than 2 hours)

17. Step 17

    Once ready to pipe, transfer the lime leaf cream to a piping bag and twist the end to seal. Holding the piping bag tightly, swing the piping bag around in a circular motion, to remove any air bubbles in the cream

18. Step 18

    Make two holes in both ends of the bottom of the choux pastry cases. Snip off the end of the bag and pipe the cream into the éclairs until they are full

19. Step 19

    To make the chocolate topping, melt the white chocolate in a bain-marie and then allow to cool slightly

20. Step 20

    Dip the pastry cases into the melted chocolate and allow to set for a few minutes before topping with the cubes of mango and lime zest
