When I devoured this little passion fruit tartelette from Financier Pastries at FlowerSchool NY a few weeks ago, who knew... 
Petit Fours, art at Etsy, 9" x 11"
I spent this week grappling with a Tuna fish sandwich and even more Parisien petit fours? C'est la vie...
Most people waltz into Champs-Elysees and head straight for the macaron counter. They completely miss the tray of mini petit fours by the cash register, but not me/mais pas moi. 
What better way to taste a little bite of everything inhouse for less calories (like who's counting) and less dough? 
These are not those horrid little sugary squares of iced yellow cake we know too well and hate, but mini tastes of framboise and religieuse bite-sized... 
I made this astonishing discovery my last morning in Paris. I raced to buy these and then raced home to shoot setups of these sweet minis.... 
Naturelement I had to eat them up before racing off to catch the plane, but they were mostly fruity anyway. *Try not to race around too much when you're bringing these babies home or they'll show serious wear and tear. They ARE delicate.
Most patisseries have these mini delights like Dalloyau. And they don't cost too much - 10 petit fours(13 euros) 
Fauchon and Gerard Mulot have them.
Yellow Bird is very fond of the mini Baba au rhume petit four... 
BEAR is not so picky and will happily settle for the whole plate BONJOUR PETIT FOUR EUPHORIA!
