One of the things that I always thought was out of the question in a city-scape was foraging for food. Now, I'm not talking about wandering through back-alleys and hoping some type of fancy restaurant has tossed away a perfectly good, yet slightly cracked batch of tasty macarons. What I am babbling about is the prospect of "urban foraging". This involves identifying trees and plants throughout the local area that are edible - from what I've seen, there are a lot of people who plant fruit trees or bushes that merely like the way it looks with no intention of eating anything from it, or that they perhaps moved into the house/ building and don't know of the existence of particular plants' wild bounty.
For me, my first experience was brought about by my roommate's excited chirps of, "There's a sour cherry tree!" This resulted in the two of us wandering down the street and picking two full pounds of the shimmering red fruit - which I found to be a thankful thing because no one, not even the person living in the lot the tree was growing in, wanted to eat these cherries! (And the gentleman told us himself by saying, "They're sour. You can pick all you want.")

(The pie before it was baked - I used a fork to decorate the edges.)
These cherries were a kind of gift as I was able to make a delicious sour cherry pie with the help of my awesome roomie. The recipes used are slightly modified versions of those from The Essential Baker by Carole Bloom (one of my favourite cookbooks by far!).
The Crust
3c all-purpose flour
2 T sugar
1/2 tsp salt
8 oz unsalted butter, chilled
1/4c sour cream, full-fat
3-4T ice water
The Filling
2 lbs sour cherries, washed and pitted
1.5c fresh rhubarb, cut into 1/2in pieces
1c granulated sugar
1/4c firmly packed brown sugar
1/2c cornstarch
Finely grated zest of 2 lemons
1 tsp vanilla extract
1. In a stand-mixer, place flour, 2T of sugar and salt. Then add butter (sliced into small pieces) and mix with paddle attachment till a crumbly mixture is achieved.
2. Add sour cream and mix until just combined.
3. Add ice water gradually (you may need to add more of less depending on the moisture content of your ingredients, the air, etc.).
4. Once a smooth ball is formed - it may be slightly sticky - place it into plastic wrap and refrigerate for a couple hours. (You may want to divide the dough into two portions and flatten into disks for ease of rolling later on, as well as to quicken the chilling process.)
5. While waiting, mix together fruits, sugars, zest, and vanilla in a large bowl. (You will be waiting till the dough is ready before adding the cornstarch.)
6. Once the dough is chilled properly, dust the surface with all-purpose you'll be rolling your dough on. Divide the dough into two equal portions (if you haven't done this already) and then roll each one out to fit the size of your pie pan before placing it into the pie pan itself. Once placed in the pan, cut the overhanging edges off.
7. You will now notice that your fruit mixture will probably have a lot of juice. I recommend scooping draining off a good quantity of the juice before sifting your cornstarch over the mixture and mixing everything together. Once this is done, put the fruit and cornstarch mixture into the pie pan.
8. Now roll out your other half of the dough and cut into strips, shapes, or whatever suits your fancy. Then arrange the pieces of dough on top of the open-faced pie.
9. You'll want to preheat your oven to 425F. Bake the pie on a cookiesheet for about 15 minutes before reducing the temperature to 350F and baking for another 40-50minutes.
And my finished pie looked like this!
