Pastry cream
- For a vanilla cream: scrape the vanilla seeds and add them to the milk along with the pod. For an orange blossom cream: mix 200 g of orange blossom water with 30 g of whole milk powder.
- Bring the milk to a simmer. Let infuse for 2 hours for the vanilla version.
- Rehydrate the gelatin in 10 g of cold water. Refrigerate.
- Mix the sugar, yolks, and cornstarch.
- Bring the milk to a simmer and gradually add it to the previous mixture.
- Pour everything back over medium heat, stirring constantly. Bring to a boil for 3 minutes.
- Off the heat, add the gelatin and mix well.
- Let cool. When the mixture reaches about 40°C, add the butter cut into cubes and mix until smooth.
- Cover with plastic wrap directly on the surface and refrigerate for at least 2 hours.
Assembly
- Loosen the mixture with a whisk.
- Whip the cream to soft peaks and fold it in gradually.
