Nectarine-Brown Butter Tart


Need a summer fruit dessert?
I'm trying to write things down in a more or less solid place because I keep misplacing my notes...
I first made a version of brown butter nectarine last year (though maybe it was peach at the time), and I can't remember where I found the "jumping off point" recipe- so I can't give credit where credit may be due- but, there were changes made a few times if that makes anyone feel better about the situation.
However, it's also very much like the peach pie we used to have in the summer when I was growing up... which I'm realizing I haven't had in years... so there's that, too.
(For now it is what it is, but I hope to try the pastry out with an oat/rice/cornstarch blend in the near future.)


You can use any stone fruit on this one, wonderful this time of year- as you choose or whatever is available to you. Make sure it's something ripe, though not overly so: nectarines, peaches, plums, apricots--- even cherries.
No matter what, you want to use a type of fruit that is intense and slightly sweet and/or tart with a luscious heavier flesh, a body to it. No flimsy fruit.
And I'd advise to always pick up a bit of extra fruit, a bit more than what is called for- just in case, you never know.
I don’t say this to brag, but the fruit here in California is fantastic... no matter what it happens to be... not that you actually have to DO anything to it, but I'm very grateful I can use it so easily.

Making this tart is not a difficult project, but you'll need to allot some time- though in my opinion it’s well worth it. The longest stint for this recipe would be chilling the brown butter filling before moving on to tart assemblage... at which point it's a very thick but still somewhat spreadable creme (referring to texture here, not content).

Look at the flecks of browned butter and vanilla in there:


You must give yourself time for this one (i.e. start it in the morning if you want to serve it in the evening, OR start it a day ahead and don't spend precious time waiting). Otherwise, if you choose not to wait, things can get a bit messy.


After baking, the filling of the tart will be puffed, browned, and slightly wobbly. But you leave it to cool and then chill. The filling settles and sets to a consistency somewhere between custardy and fudgy so it can be sliced with nice sharp edges.  


It may not be the most drop-dead gorgeous dessert you've ever seen- vibrant color suffers with the heat of baking- and it's a tad rustic... but it tastes pretty nice!
Not too sweet, but caramel-y and sweet-tart fruity with a shortbread-like crust.
It's even great for breakfast (if you do that sort of thing) with some damn fine coffee. Black.
 

You will need an 8 inch tart pan with removable bottom for this...



Nectarine - Brown Butter Tart
Serves 6-8

1/2 c (1 stick, 113 g) unsalted butter
1/2 vanilla bean (OR 1/2 t vanilla bean paste or a teaspoon of vanilla extract)
2/3 c (134 g) sugar
1 1/2 T (13 g) flour
1 extra large egg
a pinch of salt

5 T unsalted butter (71 g), at cool room temperature
3 T (24 g) powdered (confectioner's) sugar
1c plus 2 T (108 g) flour
1/4 t (scant 2 g) salt
1 egg yolk

2-3 ripe nectarines (or peaches, maybe 3-4 plums, 4-6 apricots, a bunch of cherries...)


To make the brown butter filling, melt the butter in a small saucepan over medium heat along with the scraped seeds from the vanilla pod or vanilla paste (throw the empty pod into the butter, for extra flavor). Continue heating until the milk solids begin to brown and become nutty. It'll take maybe 10 mintues- be careful because it may sputter a bit, and it can burn close to the end- so watch it!
While the butter browns, whisk the sugar and flour together in a bowl, then add the egg and whisk to combine (as well as the vanilla extract if you're using it).
When the butter is finished, remove the pan from the heat, fish out the vanilla pod or strain as you pour the warm browned butter and any toasty solids into the bowl with the sugar mixture. Mix well and leave to cool about 20 minutes before covering and chilling in the fridge at least 6 hours.

To make the pastry, blend the butter with the sugar, flour, and salt in a medium-sized bowl until you have a crumbly mass (you can use your hands for this). Add the egg yolk and work it in until you have a uniform dough- though you don't want to over work it (gently, just until it comes together). If it's not coming together very easily- err on the side of caution and undermix in this case- you can add just a sprinkle of water to help get the job done.
Bring the dough together, smash it into a thick disc, wrap in plastic or waxed paper and refrigerate at least an hour to rest.

Preheat the oven to 375 F (190 C). Lightly grease an 8" round tart pan with a removable bottom with butter or baking spray. Roll out the chilled dough between two sheets of plastic wrap or parchment paper so it will fit the pan (it'll be somewhere in the range of a few mm to 1/2 cm thick). Fit the pastry into the pan, pressing into the fluted sides, and cut off the excess with a knife. Freeze about 10 minutes (or if you're still waiting for the browned butter mixture to chill, you could place the prepared tart pan in the fridge for longer).
Prepare the fruit just before assembling. Halve and pit the fruit, and slice into thin pieces (a nectarine or peach- maybe into 12ths, an apricot- maybe 6ths... if using cherries, just pit and halve).
When ready to bake, remove the tart pan from the fridge and pour in the chilled brown butter filling. Smooth it as best you can, hitting the edges- though it doesn't have to be perfect as it will level itself out while baking. Arrange the fruit on top of the tart (I think concentric circles work pretty well) pressing the slices in gently.
Place the prepared tart on a sheet pan to accommodate any overflow and bake about 45 minutes

The tart is done when the edges of the pastry are a light golden brown and the filling is browned everywhere surrounding the fruit. The filling will be a bit wobbly. 
Place the tart on a rack and let cool to warm before placing it in the fridge to chill all the way through and set completely (this will take a couple hours).

Slice and serve the tart at a cool room temperature.
