Mushroom Piroshki Appetizers

Umami. Flavor that hits on all six cylinders. Mushrooms have it. And until a few years ago, I admit that my misunderstanding of mushrooms led me to dislike and avoid them. Thank goodness I've moved past that, because YUM. 

With a few simple steps, even common brown mushrooms can deliver powerhouse flavor, and in this case, kick the butt of the beef piroshki I made to accompany these mushroom ones for Easter. 

Mushroom 101

• Selecting Fresh Mushrooms: How can you tell? See the photo above? Fresh mushrooms will have a smooth, glossy cap, that (for the most part) will not have come away from the stem. Like all produce, use it ASAP for the best results. 
• Storing - A Cool Dark Place: Store in a paper bag in a low-humidity drawer in the fridge.
• Washing: YES. Wash off the dirt, for they grow in the ground. Just rinse them under some cool water, and gently rub off any dirt. Allow them to dry, then use them as desired. 

Makes about 50 bite-sized piroshki 

The Dough
4oz cream cheese (just half of a regular old brick), at room temp
4 oz (1 stick) unsalted butter, at room temp
1 1/4C AP flour
1/2t kosher salt

Cream the butter til smooth. Add the cream cheese, and cream til combined. Stir in the flour and salt to form a ball. Flatten it out into a rectangular slab about 1/2" thick, wrap in parchment or plastic wrap, and chill for about an hour. 

The Filling
3 8oz packages organic brown mushrooms 
1 small, or 1/2 large white or yellow onion
2T olive oil
1T butter
salt & pepper 
sherry (optional)

1 beaten egg to seal the piroshki, and for an eggwash

For this recipe, we'll use the whole mushroom. Trim off the ends of the stems. If you have a food processor, you're very happy right now. Chop the shrooms in batches of 3 on "pulse" til finely diced. Otherwise, grab a sharp knife and go to town. Finely dice the onion. Heat a large skillet on medium-high, heat 2T olive oil, then saute the onion til golden. Remove from the pan. Turn heat to high. 

Dump the chopped mushrooms into a cheesecloth or clean kitchen towel (it will turn brown) and squeeze out as much liquid as you can, saving it in a jar for later use (I froze mine to use later in a soup or sauce). Dump the mushrooms into the hot pan, and saute, stirring constantly for even browning. Sprinkle with about 1/2t salt and freshly ground pepper. Saute for about 10 minutes. If you have some sherry, drizzle about 2T over the shrooms to deglaze the pan (about 1 minute). Add the shrooms to the sauteed onions, dot with butter, and allow to cool, stirring occasionally to let off steam. Taste the cooled filling. Add more salt & pepper if needed. 

Roll the Dough
Dust a clean work surface lightly with flour. This dough isn't very sticky, so you only need a little flour to help roll out your dough to about 1/16." Cut silver dollar-sized discs and place them on a parchment-lined baking sheet. 

My dough cutter is 2" in diameter 

Fill and Shape
Take a disc of dough and using your finger, brush some beaten egg around the inside edge. Scoop a full spoon of filling onto the center. Fold the disc in half like a taco. Press the edges together, then crimp the edge to further seal it. 

If making ahead, freeze the piroshki on the sheet pan, then transfer to a freezer-safe bag. 

unbaked frozen piroshki. space them out farther when baking.

Baking
Preheat oven to 400'. Space out piroshki on a parchment-lined sheet pan. Brush with eggwash, and bake until golden brown. Serve hot. 

my test bake popped open, so I added some eggwash to the seal. either way, they're delicious!

The Best Veggie Gyoza

Why make your own gyoza, when Trader Joe's sells bags of them for just a few bucks? 

Try them, and you will never again accept lousy store-bought substitutes. These are 1,000x better, and truly easy to make. I know I say that about some things, and people stare at me like "you're a freaking trained chef", but really, your kids could make these. 

If you really needed to, you could probably get all the ingredients at Safeway. 

The filling is super basic:

napa cabbage, 1 medium

carrots, 2 medium 

fresh shiitake mushrooms, 8oz. (crimini will do in a pinch, but don't have nearly as good a flavor)

green onion 

The wrappers are relatively interchangeable. You want a very thin, square or round fresh wheat-based Asian wrapper. Most grocery stores (in the Bay Area anyway) now carry at least one type of wrapper in the fresh/fridge case (try near the produce section at Safeway). Whole Foods has more than one kind (they have a cold case near the eggs with Asian noodles, etc.), and Asian specialty stores will have a bigger selection. If you like to cook Asian meals, I recommend going to an Asian specialty store and stocking up on some condiments. Fun! A basic traditional dipping sauce for these would be equal parts of soy sauce and rice vinegar. I always thin that out with some water (even if I start with reduced-sodium soy sauce). No one needs that much sodium, and you won't know the difference. 

Prep the Filling

Shiitake mushrooms have thick, meaty caps, and tougher stems. I generally use just the caps, and dry or freeze the stems for another use (like fortifying broths). Contrary to popular belief, you should always rinse mushrooms before using. They grow in the ground, you know. Just run them under some cool water, and use your fingers to gently rub off any dirt. Shiitake are very sturdy, and can take the abuse. Slice the caps in half across their width, then stack them back together like a hamburger; then slice thin slices. This way you'll have thinner strips, and more of them dispersed in your filling.

Remove the outermost leaves of the cabbage. Slice the cabbage in half lengthwise. Use a knife to slice very thin shreds down to the base (like you're shredding cabbage for coleslaw). 

Wash, peel and grate the carrots. 

Rinse and thinly slice two green onions. 

Heat a large skillet (I use a 12" for this) on med-high. Add 2T olive oil. Add the mushrooms, and saute for 3-4 minutes, until brown. Remove from the pan. Add the carrots, and saute for a few minutes until they're heated through and dry. Add the cabbage. Saute for just a few minutes until the cabbage wilts down. Remember, this filling will cook again when you cook the gyoza, so better to leave the veggies tender for now so they don't end up mushy. Stir in the green onion and mushrooms, and dump the filling into a large bowl to cool. Stir it occasionally to help steam escape so it cools faster. 

Assembly

Set out some baking sheets or large trays. Pour a little cold water into a small bowl (you'll use this to seal the wrapper). Put one some good music, or Mad Men, or whatever, and start wrapping. 

Using a fork, fill each wrapper with enough filling to cover about 1/4-1/3 of its area, leaving the edges free. Dip your finger in the water, and rub it around the edge of the wrapper. Fold the wrapper in half like a taco, and pinch the seam together firmly, going back over it a couple of times. Set the gyoza on the sheet, and keep that factory cranking. 

These are round wrappers. You can crimp the edge for a fancy effect.
With square wrappers, you can just seal them in half.

If you're going to eat tonight, wipe out the pan you used for the veggies, and heat it to medium. Add 1T olive oil and 1t toasted sesame oil (optional, but DO IT). When the oil is hot, place the gyoza seam-side up in a spiral formation, so they help each other stand up (and you can also get more in the pan that way). Brown the bottoms, then add about 1/2C water to the pan, cover, and reduce the heat to low. When all the water is evaporated, remove the lid, turn up the heat for a minute until they sizzle. Serve immediately with your favorite dipping sauce.

Freeze remaining gyoza on the sheet pan, then once frozen, transfer to a ziploc bag, and store for up to 3 months.
