This is woefully out of date, and I don't even have any pictures of it, but it goes with my last food-related post, so I just wanted to finish it up and be done with it. For what it's worth, I'm sure this galette could easily be made more seasonal - apple and orange anyone?
When I made the tomato and goat's cheese tart I figured there was a chance I’d have leftover tart dough, so bought berries to be prepared. I chose blackberries simply because they were on sale and looked nice. I'd love to say I picked them myself or even that they came from our Farmers' Market, but no, these were straight from Tesco. Oh well. I was trying to figure out what I could add to them to give the pie that something extra and saw a lime in the fridge. I was sure I’d seen that combination somewhere. Sure enough, I had but not in a pie. According to Google, blackberries seem to go well with lime in a pie situation, but most use them on top of a key lime pie/lime tart sort of thing, or part of cheesecake. I figured there was nothing to lose by trying a bit of lime zest and juice with the berries, and sure enough I was right.
Blackberry lime galette
I used another blackberry galette recipe for guidance on amounts of sugar and cornstarch, and the dough as already mentioned was from the David Lebovitz tomato and goat's cheese tart recipe.
Leftover tart dough (this was about 11-12 inches in diameter when rolled out)
Just under 1 1/2 cups blackberries
Zest of 1/2 lime
Juice of 1/4 lime
1 1/2 Tablespoons sugar (I like mine quit tart; if you’re into sweeter things, go for more)
2 teaspoons cornstarch (I read a few things on using cornstarch vs flour for thickening, and got the sense that, when it comes to pies cornstarch is better. If you prefer flour, supposedly you need to use twice as much.)
milk (or egg wash; I really hate wasting an egg for this purpose though)
Raw/demerara sugar (about 1/2 Tablespoon)
Roll out your dough so that it's roughly 1/8-1/4 inch thick. You're going for rustic, so no need to make a perfect circle. Transfer to a baking sheet lined with a Silpat mat (or if you don't have one, I am sure parchment or just spraying the sheet with cooking spray would be fine). Gently mix blackberries, lime juice and zest, 1 1/2 T sugar and cornstarch and pile onto the middle of the dough, leaving about a 1 inch border. Fold the edges of the dough over the filling, brush exposed dough with milk (or egg wash) and sprinkle with demerara sugar. Bake at 175 C (350 F) for about 30 min, or until the crust is golden.
Word of warning: steamed lime juice is apparently bad on the eyes – be careful when opening the oven the first time!!
