In one sentence, describe what the following article is about: Warm tea has long been a remedy for sore throats, but it can also help keep your voice from becoming strained in the short term or damaged in the long term. Liquids that are too hot can be bad for your throat, and drinking liquids that are too cold before performing can hurt your vocal. Poor hydration can lead to permanent damage in your vocal folds. If you plan on rapping professionally, you should take frequent water breaks to protect your voice. Licorice and peppermint teas are recommended for your voice. Peppermint tea will cut down on gnarly phlegm that give your voice a garbled tone, and licorice tea will numb and sooth your throat, which is excellent if you have to perform night after night. You should avoid sprays that numb your throat. These can lead to you pushing your voice too hard, which can result in permanent damage. However there are some hydrating brands, like Entertainer's Secret and Vocalise, which should be available at your local drug store. Keep one of these products handy and use it regularly when practicing and performing. Your voice is just like any other muscle, and using it too much or pushing it too hard can lead to serious trouble. This could be something as simple as hoarseness or voice loss, which can usually be remedied by resting your voice until it returns to normal. But this can prevent you from going on stage, recording, or practicing! It's better to take a few short breaks than lose an entire day of practice/performing because you need to rest your voice. If you feel tightness, pain, or a change in your quality of voice, it's likely a sign that you need to take a break. Even when you're getting fired up and you really want to tear loose with your voice, you should avoid yelling or screaming. This can tire out your voice or even cause it damage. Instead, use mic techniques to imitate yelling and screaming without doing harm to your voice. Smoking tobacco will cause damage to your vocal folds over time and drinking alcohol will dehydrate your vocal folds, making them more prone to damage and strain. Avoid food that causes heartburn. Over time, the stomach acid from causing your heartburn could also harm your voice.
Summary: Drink warm, soothing liquids. Use vocal sprays to restore and preserve your voice. Take frequent breaks when rapping. Use the mic to your advantage when able. Avoid voice damaging substances.

Use a standard saucepan over medium-low heat. Your goal with this sauce should be to gently bring it to a warm temperature and a smooth consistency. Low, slow cooking is best. This can take patience. Gently stir the mixture as you add the ingredients to keep them from burning or sticking. Continue stirring to combine. If you can, use fresh-grated Parmesan. The taste difference is noticeable compared to using pre-grated cheese. Fresh cheese also tends to be less vulnerable to "seizing." See below for an explanation. Wait until the sauce reaches a gentle boil. Just a few small bubbles will be forming. At this point, start gently stirring until it becomes noticeably thicker. This is usually about eight minutes. Resist the temptation to crank up the heat. Turn it down if you notice your sauce boiling rapidly. Not only can this burn your ingredients and produce an unpleasant bitter taste it can also make your cheese "seize". When cheese is heated too quickly, the proteins in the cheese coil up rather than separating gently. This separates the fat and moisture from the cheese, leaving an unpleasantly hard product that refuses to melt. The sauce is ready to season when it's at a pleasantly thick consistency. You can add whatever seasonings you want, but plain old salt and pepper work great on their own. Stir to mix evenly after adding. A few shakes or pinches of each seasoning should do the trick. If you're worried about adding too much, try adding just a single pinch, stirring, and tasting the sauce. Repeat until you're satisfied! If you saved the water from the pasta pot, you can use it to thin out a sauce that is too thick and rich. The water retains some of the flavor of the pasta, giving the sauce a nice "bready" flavor while thinning it. If you accidentally add too much water, just simmer it a little longer to thicken it again. When the sauce tastes just how you like it, it's ready to serve. Spoon steaming portions over your favorite pasta. The recipe in this section should serve about six. Alternatively, try using it to lend creamy flavor to your favorite meat and vegetable dishes, including chicken, shrimp, broccoli, and much more. This sauce's mild flavor is highly versatile, so you can use it for almost any entree.

One-sentence summary -- Melt butter on the stove. Stir in the cream and Parmesan cheese. Heat until simmering. Add salt and pepper to taste. Optionally, use the pasta water to thin the sauce. Serve!

Problem: Article: Certain kinds of spruce trees are common to certain locations. Note where the tree is located and research the kinds of spruce trees native to the area. Find an illustrated guide of trees in your region to help you identify the species of spruce. The Colorado Spruce is common throughout the Pacific Northwest and the Midwest. The Red Spruce, The Black Spruce and The Blue Spruce are all common varieties that typically grow in the Northeast. The White Spruce and the Norway Spruce are prevalent both in the Northeast and the Northwest. There are also several varieties of spruce that are native to countries in East Asia, Turkey and areas of Western Europe. Different spruce species flourish in different conditions. Some spruce trees tend to grow only near water sources or places with rich soil, while others do well even in harsh climates. Take into account the area in which the spruce is growing. The Colorado spruce grows best in environments that have rich, gravely soil like the areas around rivers or streams. The Black Spruce typically grows in bogs and swamps, which is why it is also referred to as the Bog Spruce. The Red Spruce is often found in cool forests alongside other conifers. The White Spruce tends to grow in moist acidic soil around rivers or streams and often grows around other coniferous hardwood trees. The Norway Spruce can grow in a variety of cooler climates, but flourishes in moist and acidic soils. If you are trying to identify a Christmas tree, you may not know where the tree came from.

If you didn't purchase it from a store or nursery, you will have to look closely at the tree to identify it. The most common spruces used as Christmas trees are the Colorado Spruce and the White Spruce.
Summary:
Use the region to narrow down the species. Consider the immediate area. Ask the nursery to identify a Christmas spruce.
