For the best results make 85 g brown butter using the butter stated in the recipe
Heat butter in a saucepan on medium heat, first it will melt then it will foam. It is ready when the white bits on the bottom of the pan turn into golden brown and it has a nutty smell. Make sure you carefully watch it throughout the process, stir regularly and remove from the heat before it starts burning. Let it cool to room temperature
In a bowl whisk together eggs and sugar until pale and foamy for min 5 minutes
Sift in flour and baking powder then gently fold together
Fold in earl grey tea leaf
Fold in orange zest
Last, fold in brown butter, cover the bowl and leave it in the fridge for a few hours or even better if overnight
Next day take the madeleine batter out of the fridge
Gently grease your madeleine tin first with butter then dust with flour
Ideally using a piping bag fill the madeleine tin till ⅔
Pop the tin into the freezer while pre-heating oven to 200 C / 392°F
Bake for 5 min in 200 C / 392 F then for another 5 min in 160 C / 345 F. The high temperature will help to achieve the classic "bump" style then the lower temperature bakes them into an even golden colour. Feel free to experiment with your own oven for the best results.
Once baked, immediately remove the madeleines from the tin and serve while still warm with tea or coffee
