3. Put the egg, lemon juice, and sugar in a heatproof bowl and mix. Put on a double boiler and continue mixing with a whisk.
4. When it becomes just a bit softer than custard (about 83℃), remove from the heat and continue mixing.

Story Behind this Recipe

Using the lemon macaron filling recipe from Pierre Herme's book "Macaron" as reference, I came up with a sweet and sour version using less sugar and lemon juice. Mr. Herme's "Macaron" book is an indispensable macaron bible!
