Floured chicken pieces in a lemon, wine and caper sauce over angel hair. Four servings.
The source browns it five minutes per side, then returns it to simmer another fifteen. For breast pounded thin and cut into two-inch pieces, that is a great deal of cooking.
Thin chicken pieces are done in about three minutes per side. Another fifteen in simmering liquid takes them well past tender and into dry and stringy.
Better sequence: brown three to four minutes per side, remove, build and reduce the sauce for the full fifteen minutes on its own, then return the chicken for the last two or three minutes to warm through and absorb the sauce.
Chicken should reach an internal temperature of 165F, which the source never states.

Its ingredient list says the angel hair is cooked and drained, and then step nine cooks it.
Uncooked is what you buy. The pasta gets boiled four to five minutes near the end, timed so it is ready when the sauce is.
Angel hair cooks very fast, so start the water early and drop the pasta once the sauce is reducing.
Which the ingredient list assumes and the method never mentions.
A chicken breast is thick at one end and thin at the other, so an unpounded piece cooks unevenly no matter how careful you are. Pounding to a consistent thickness fixes that.
Put it between two sheets of plastic wrap and work from the centre outward with a rolling pin or the flat of a heavy pan. About a quarter inch is right here, since the pieces are then cut small.
One minute until golden and fragrant, then transferred to a plate.
Garlic burns in the time it takes to brown chicken, and burnt garlic turns the whole sauce bitter. Removing it protects it, and it goes back in later with the broth.
Golden and fragrant is the cue. Brown is too far.
A cup of wine poured in and boiled hard, scraping the bottom with a wooden spoon.
Those browned bits stuck to the pan are concentrated flavour from the chicken and the flour coating, and wine dissolves them in a way water would not.
Scrape properly. Anything left welded to the pan is flavour you paid for and did not use.
About five minutes at a hard boil.
A cup of wine unreduced would make the sauce thin and sharply alcoholic. Halving it concentrates the flavour and cooks off most of the alcohol.
Dry white is specified. Something you would drink; a sweet wine throws the balance against the lemon.
Two tablespoons stirred in with the parsley after the sauce has cooked.
This is the standard finish for a pan sauce. Butter swirled into a sauce below boiling point emulsifies and gives it body and shine. Boiled, it splits into oil.
The other two tablespoons went in earlier for cooking the chicken.
A third of a cup with pepper and paprika, coating the chicken evenly.
That thin flour layer does two jobs: it browns readily, and it thickens the sauce as the chicken sits in it later. It is the only thickener in the recipe.
Shake off the excess. A thick coating goes gluey rather than crisp.
Two tablespoons.
Capers are the sharp counterpoint to a cup of wine and a quarter cup of lemon juice. Drain them but do not rinse; that brine is part of the seasoning.
At 385mg of sodium per serving this is moderate, and the capers are most of it.

The chicken goes onto a dish with a few spoonfuls of sauce over it, then the pasta is tossed in the pan with the remaining sauce. Plating the pasta first and the chicken on top keeps the coating from going soggy.
The source notes the sauce suits veal medallions, which is the traditional piccata. Veal cooks faster still, so two minutes per side is plenty.
A classic chicken piccata with capers and lemon, served over angel hair.
The source cooks the chicken 5 minutes per side then simmers it another 15, which is far too long for breast pounded thin and cut into 2-inch pieces and gives dry stringy chicken. Brown 3 to 4 minutes per side, remove, reduce the sauce for the full 15 minutes on its own, then return the chicken for the last 2 to 3 minutes. Chicken should reach 165F, which the source never states. The source ingredient list describes the angel hair as already cooked and drained while step 9 cooks it; buy it uncooked and boil it 4 to 5 minutes near the end. Remove the garlic after its minute so it does not burn during the chicken browning. Reduce the wine by half. Add the final butter off the boil so it emulsifies rather than splitting. Shake excess flour off the chicken.
