This classic French pastry is super easy to make last minute or even when sudden guests have already arrived! The combination of a crispy puff pastry bottom and a tasty but simple frangipane cuts right into the sweetness of the plums, creating a treat that is welcome any time of day.
Swap the Mirabel plums for other (stone) fruit you prefer; green apples works really well too. I usually make my own puff pastry, because it freezes well so you can prepare in advance, but it just depends on how picky you are and store bought or frozen might work for you as well. Same goes for the almonds: I like to roast and ground almonds myself, but if you have access to prepacked and prefer that, it obviously will work too.
