If you already know what angle your knife is sharpened at, you'll probably wish to sharpen it at this angle again. Sharpening at a different angle will take significantly more time and may take a few goes before any rough angles are smoothed out.  If you don't know the current angle, ask the manufacturer of your knife or inquire at a knowledgeable knife shop to determine what angle is appropriate for your knife. If you have to make a gut decision, choose an angle of 10° - 30° per side. Shallower angles make a sharper edge that doesn't last as long; steeper angles are more durable, so 17° - 20° is a good compromise between the two.

Problem: Article: Purchase several ripe apples, then eat them or cut them until you reach their cores. Carefully remove the seeds from around the cores of the apples, being sure to pick out every seed before disposing of the cores.  Be aware that most apple trees grown by farmers and gardeners come from grafted trees, and are not planted directly from the seed. Planting trees from apple seeds produced highly variable fruit, since apple trees are not guaranteed to grow according to their type or variety. The more seeds you plant, the more likely it will be that one of the trees will produce edible apples, as opposed to less edible varieties like crab apples. There is about a one in ten success rates of seeds growing into apple trees that produce fruit good enough to eat. Try to start the process of preparing the seeds during the fall, so that by the beginning of spring, the seeds are ready for planting. After you extract the seeds from the apple or apples, add the seeds to a bowl of water. If they float, throw them away, because they are less likely to grow. Lay the other seeds out on a paper towel and allow them to dry for three to four weeks. Flip the seeds over every two days so that they dry evenly on both sides. After a couple days of drying, purchase some peat moss. Pour a few tablespoons of the peat moss on the paper towel, then sprinkle on a few drops of water. Use your hands to mix up the peat moss and seeds. After you mix up the seeds and peat moss, pour the mixture into a ziplock bag. Write the date on the bag with a marker, then place the bag in the refrigerator for three months.  The process of storing the seeds in moist, cold conditions is called stratification. Stratification softens the hard outer coat of the seed and encourages the embryo inside the seed to start germinating. After three months, remove them from the refrigerator, and allow them to warm up so that you can plant them.
Summary: Remove apple seeds from the cores of several apples. Dry the seeds on a paper towel. Mix the seeds with peat moss. Put the seeds and peat moss in a bag and refrigerate.

Article: Add the vegetable or olive oil to the skillet and heat over medium-high until the oil becomes glossy and smooth enough to easily coat the entire pan. Sprinkle both sides of the chops with equal amounts of salt, pepper, and Italian seasoning blend. Gently pat the chops to rub the seasonings into the meat. Cook the chops for 2 minutes on each side in the hot oil, or until each side is notably browned. The process of searing and braising pork chops on the stove can go a long way in preventing the meat from drying out. The seared surface locks in more of the pork's natural moisture, while the braising liquid infuses the meat with additional moisture as it cooks. Pour the broth into the pan and bring it to a steady boil. Let the chops sit in the broth at a full boil for 30 to 60 seconds before proceeding. This way, the broth will have plenty of time to reach a good heat. Cover and reduce the heat to medium-low. Let the chops simmer for about 20 to 25 minutes.  To accurately determine whether or not the pork chops are safe to eat, check the center of the thickest chop with a meat thermometer. The internal temperature of pork chops must reach at least 145 degrees Fahrenheit (63 degrees Celsius) before the pork is safe to eat. If you do not have a meat thermometer, you can determine if the pork chops are done by cutting into the center of the thickest cut. If the meat is white, it is likely safe to eat. Note, however, that if you use a braising liquid that has color to it, the color of the liquid can tint the meat. As long as the inside of the pork does not look pink and “rubbery,” however, it should be safe to eat. Let the pork chops rest for roughly 3 minutes before placing on individual serving plates and enjoying.
Question: What is a summary of what this article is about?
Heat the oil in a large skillet. Season both sides of the pork chops. Add the pork chops and sear them in the hot pan. Add the chicken broth. Simmer until done. Serve hot.
