Put the butter and honey in a saucepan and let it foam until it turns golden brown and smells like caramel and hazelnuts (how it really smells in paradise).
Whisk the eggs with the two types of sugar and lemon zest for 10 minutes until it has doubled in volume. It should be nice and white and frothy.
Pour in the warm honey mixture in a steady stream. Then sift the flour over it and stir vigorously until all lumps are dissolved. Refrigerate for at least three hours (it can also be overnight) to set.
Preheat the oven to 190 °C.
Grease the madeleine baking mold and divide the batter into the molds. Do not fill them too full, as the batter will rise. Bake for 12 to 15 minutes in the preheated oven.
Drizzle with a teaspoon of lemon juice and let cool.
