Vanilla ice cream

5. Pour this preparation back into the pan and thicken over low heat, stirring continuously using a large wooden spoon.
6. When the cream begins to coat the spoon, remove it from the heat.
7. Let cool and finally add the heavy cream.
8. Add the preparation into an airtight glass container and place it in the freezer.

Syrup

1. Bring the water and sugar to a boil.

Meringue

1. The day before, crack the eggs and separate them. Reserve the egg whites in a bowl covered with plastic wrap and let them age outside the fridge overnight.
2. In the bowl of a stand mixer, start beating the egg whites at medium speed until they become frothy.
3. Then add a tablespoon of caster sugar and 4 drops of lemon juice.
4. Beat for about 1 minute at maximum speed so that the sugar has time to dissolve in the egg whites.
5. Add a second spoonful of caster sugar, and continue beating. Add the remaining sugar gradually until it is dissolved.
