To achieve this perfection, you need just a few ingredients, but the highest quality. Precision is everything here! 
- 6 large eggs (essential: separate the yolks from the whites very carefully)
- 100g of cake flour (type 00, sifted!)
- 100g of high quality unsalted butter
- 100ml of fresh whole milk
- 100g of granulated sugar (or icing sugar for an even silkier texture)
- 1 teaspoon pure vanilla extract
- A pinch of salt
- A drop of lemon juice (to stabilize the meringue)
