So just a basic chicken night tonight. But I thought I would cover the basics of making a pan sauce for anyone that is interested and doesn't know the technique. This one is a basic white wine reduction. If you already know how to do pan sauces, skip on by :)
So I start by searing the chicken breast with just a bit of olive oil in the pan. I don't want to add too much flavor to the breast itself since I'm making a sauce so just sprinkle both sides liberally with salt and pepper. For the heat on the pan, the oil should be kinda wavy like the bottom of a swimming pool but not smoking. If the olive oil smokes, throw it away and start over, it'll be very bitter. Sear the breast so that it has a nice little bit of carmelization on each side. Also, I sear the edge on the thick end so there is good color.
Once I pull the chicken out of the pan and into a 375 degree oven, I use a little white wine to deglaze (scrape the meat bits from) the pan. maybe 2-3 oz. Then I pile my aromatics in. In this case, a couple of shallots sliced thin, half a Spanish onion and about 3 cloves of garlic that I smashed to let the juices out. I'm still at med-high heat through this whole process.
When the onions turn translucent, I add the rest of the white wine, in this case about 16 oz total. The amount of wine isn't really that important as long as you use the same amount of chicken stock (later). I bring the wine to a fast simmer and let it sit there for about 10 minutes. When the wine is nearly gone, I add the chicken stock and my herbs (rosemary, thyme leaves and a couple of ancho chile rings) and mix it together. There are classic flavor combinations that you can use here or you can get adventurous. There's a pretty good book called The Flavor Bible that talks specifically about complimentary flavors and gives you a list of what goes with what. Adventurous is more fun, but you can really make mistakes if you don't think about what's happening to the flavors. When you reduce your sauce like this, the flavors concentrate. One of my first reductions was awesome...awesomely inedible. I used a whole chile and when it reduced, that was all you could taste. Anyhow, I check the temp on the chicken, I'm looking for about 155. Since it was ready, I pull it out and put it on a wooden board to rest. The chicken will still keep cooking while it is sitting there so it will be safe to eat. If you are going to serve it straight out of the oven without resting (NEVER DO THIS!) you need to get the temperature up to at least 165F measured in the thickest part to make sure it is safe to serve. BTW, chicken is still slightly pink at 165, it's safe, go for it.
Once the stock finishes reducing, it will be thick enough to coat a wooden spoon (called nappe) . If you don't want to wait for the sauce to fully reduce, you can add a bit of corn starch to cold water and stir it until it looks like very thin skim milk. About 8 oz of water for 2 Tbsp of starch. Strain all the stuff out of the sauce, rinse and wipe your pan and put the sauce back in it.
Add salt and pepper to taste and add the corn starch if you are using it. Bring it to a boil and then lower to a simmer for about 2 minutes to activate the starch. Then strain it one more time and serve. I used corn starch so I could show it.
When you serve a sauce like this, you don't need much, there's a LOT of flavor in it. I just drop enough to make sure that the person runs out of sauce at the same time they run out of meat.
Start to finish, this meal took 45 minutes including prep (not counting making the stock and breaking down the chicken). I love pan sauces because they are easy, flavorful and they look good too. Here's another one I did recently using the same method, but it's a red wine reduction. BTW, any acid... wine, vinegar, fruit juice... will do, it doesn't have to be wine. Please ignore the spot on the plate, the one down side to using corn starch is that you have to "paint" the plate right, if a couple of drops spill in the wrong place, they don't wipe up.
