Financier

Method

1. 1 Melt the butter until it turns a chestnut brown and smells like roasted nuts, strain out any solids, and let it cool down to 40 degrees Celsius.
2. 2 Brown butter is the essence of financier; if the butter is only melted and not browned, the cake will be bland.
3. 3 Mix the almond flour, powdered sugar, all-purpose flour, and salt together, then add the unwhipped egg whites and stir gently.
4. 4 Pour in the brown butter, mix well, and let the dough rest in the refrigerator for 1 hour.
5. 5 Pour into a mold, sprinkle with sliced almonds, and bake at 200 degrees for 14 minutes until the edges are crispy and the center is moist.
