Why it works: Pistachio and biscuit share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 53 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Royal Trifle
Ingredients
Directions
Layer the ratafias at the bottom of a deep glass dish and sprinkle with brandy.
Spread the jam over the ratafias, then add a layer of Savoy biscuits sprinkled with sherry.
Boil the milk, then add it to the beaten egg and return to the pan, stirring in a pan of boiling water until thickened.
Sweeten the mixture and add a few drops of vanilla, then pour it over the biscuits.
In a bowl, combine the cream, 2 pints of cold water, sugar, and lemon juice. Whisk until frothy.
Skim the froth off and drain it on a sieve. Continue to whip and skim until no more froth rises.
Pile the froth high on top of the biscuits and decorate with meringues and candied fruit just before serving.
