Step 1
Melt the butter in a small saucepan on a medium low heat. Be careful not to burn the butter.
When the butter has melted add a squeeze of lemon juice (I experimented with lime as I didn't have lemon at home) and a pinch of salt. Remove the saucepan from the heat and allow the butter to cool.

Step 2
Break the eggs in a large bowl. Pour in the 100 g caster sugar and whisk slowly for 1 minute.
After that, whisk 15 g milk into the mixture until well incorporated into light yellow colour.


Step 3
In a large bowl, sift 100 g all-purpose flour, ¼ tsp salt, 3 tsp baking powder, and 1 Tbsp (6 g) matcha (green tea powder).
Sift these dry ingredients again into your bowl over the egg and sugar mixture and whisk gently until the flour is fully incorporated.


Step 4
Now slowly pour in half of the cooled melted butter. Blend the butter and mixture well before you add the rest of the butter. Then whisk again until you have a smooth batter.

Step 5
Cover the bowl of batter with plastic wrap and refrigerate to rest the batter for around 2 hours


Step 6
Melt the 1 Tbsp butter in the microwave. Coat your madeleine pan with melted butter and brush butter into each mold with a pastry brush. Then, lightly dust 1 Tbsp flour over the molds with a fine-mesh strainer.
Preheat the oven to 375°F (190°C).
Step 7
Scoop the batter with a tablespoon and transfer the batter into each mold with the help of a rubber spatula. No need to smooth out the batter in the mold as it’ll melt in the oven.

Step 8
On the centre rack, cook the madeleines for 10 minutes starting on high heat at 220 °C (428 °F) for the first 3 minutes then reduce the heat to 200 °C (392 °F) and bake for a further 6 to 7 minutes.





Remarks:
Preheat: For a convection oven, reduce cooking temperature by 25ºF (15ºC).
