Paris-Brest with caramelised buttermilk mousseline & pickled apple, apple sorbet and citrus herbs
For the sorbet, replace pears with an equal amount of apples.
Caramelised buttermilk mousseline
150ml heavy cream
75g sugar
4 egg yolks
25g all-purpose flour
25g corn starch
350ml buttermilk
150g softened butter, divided
Slowly caramelise the heavy cream on a nonstick pan over medium high heat, scraping the bottom once in a while, until the cream turns a a light caramel color.
Whisk together sugar, cornstarch, flour and egg yolks until no lumps remain. Whisk in buttermilk and caramelised heavy cream. Pour into a saucepan and bring to a boil, cook while whisking rigorously for a few minutes to thicken the cream and cook out the starches. Remove from heat and transfer to a bowl. Stir in 75g of butter until combined, cover with clingfilm and let cool. When the cream is room temperature, whisk in the remaining 75g butter and transfer to a piping bag with an open star nozzle. Store in the fridge until ready to serve.

1 Tbsp apple vinegar
A few sprigs of verbena, lemon balm and lemon thyme
Bring sugar, water, vinegar and herbs to a boil, and boil for 3-4 minutes. Remove from heat, cool for 15 minutes then add apple balls. Leave for 5-10 minutes, check to make sure apples are not mushy, then remove apple balls from pickling liquid.

Add milk, water, butter, vanilla bean if using, sugar and salt to a pan and warm up over low heat until butter is melted. Bring to a boil over medium high heat and remove from heat as soon as the milk mixture is boiling. Remove vanilla bean and rigourously whisk in flour until a homogenous paste, return to low heat and cook the dough for a few minutes. Be careful not to scrape off the thin film that forms on the pan.
Transfer dough to a bowl and leave to cool for 5-10 minutes.

Bake for 30-35 minutes, until puffy and golden brown all over. Leave to cool completely on a wire rack.
