Just in case I haven't yet persuaded you to use your leftover egg whites to make financiers, here I am again with another version. I went with pistachio this time.
Is it just me or do you also gravitate towards things pistachio-flavored when you go to a bakery or pastry shop? Is it the color? Or maybe just that it's a little bit more unusual, a flavor we're less likely to make at home? Whatever the reason - when we go to a bakery, it's always chocolate, coffee, and pistachio that we go for (and hazelnut as well for me)! Like with macarons - we can never resist trying a pistachio one and for some reason, we always end up raving about it (whereas chocolate macarons can be unpredictable and even disappointing)!
I like making the batter the night before (or up to 3 days ahead) and baking these tea cakes fresh for breakfast the next day. My fellas love them! I generally prefer savory when it comes to the first meal of the day but this is one sweet item I enjoy savoring over breakfast.
So...pistachio financiers with a cup of coffee for breakfast, it was! They were just delicious. Now, I know you have no problems using up any egg whites you might have for omelets and whatnot but...please...give financiers a try one day if you haven't already. I don't think you'll regret it!
