The almond Financier pastries are not only delicious but also a genius way to use up those leftover egg whites that often get discarded. Waste not, want not! These delightful treats are a classic French delicacy that will transport you to the streets of Paris with every bite. The name financier is said to derive from the traditional rectangular mold, which resembles a bar of gold. Another speculation says that the cake became popular in the financial district of Paris surrounding the Paris stock exchange. Nowadays, these French almond cookies are proposed into different shapes and sizes. Made into custom petit fours, base for tart or individual servings, financier is not only one of the best treat but also the easiest pastry to make. The 2 key ingredients in this recipe are, of course, the almond flour but also the brown butter (beurre noisette). Its nutty and rich flavor adds depth to the pastries, making them truly unforgettable. We will also use a hint of vanilla extract to elevate the taste even further, creating a symphony of flavors in every bite.
