Pour the tarragon vinegar into a small saucepan and whisk in the white wine, coarsely crushed peppercorns, and 1 finely diced shallot. Turn the burner to high so the liquid comes to a rolling boil. Keep boiling the mixture and whisk it occasionally until half of the liquid evaporates. Keep an eye on the mixture because it reduce within a few minutes. Turn off the burner and let the reduction cool a little before you whisk in the remaining sauce ingredients. If you add the remaining ingredients while the reduction is very hot, the sauce could curdle. Put the saucepan back on the burner and turn the heat to medium-low. Whisk in the eggs 1 at a time and then the fresh lemon juice. The sauce should be thin and combined. Whisk in 3 tablespoons (42 g) of the softened butter until it melts and incorporates into the sauce. Continue to whisk in the rest of the softened butter 3 tablespoons (42 g) at a time until it's slowly combined with the sauce. The sauce will thicken as you whisk. Once the sauce is thick enough to stick to the whisk, turn off the burner and whisk in salt and pepper according to your taste. You'll also need to whisk in 2 to 3 tablespoons (3 to 5 g) of fresh minced tarragon leaves. If the sauce isn't as thick as you'd like it, continue to cook it over low heat for 1 to 2 minutes.

Article: of every day. In order for your hair to stay soft and smooth, it needs the natural conditioning of sebum, the oil that your scalp produces to keep your hair strong. If you wash your hair every day, you rinse away this nourishing oil, leaving your strands feeling dry and coarse instead of smooth and silky.  Find the washing routine that’s right for you. Some people do it 2 or 3 times a week, while others wash every other day if their hair is especially oily. If your hair looks or feels greasy in between washed, apply dry shampoo to the roots. Massage it in to your scalp, then gently brush your hair to distribute the product. It might be hard to wash your hair in ice-cold water, but if you want silky, smooth hair, make it as chilly as you can take. Cold water helps the hair shaft lie flat, so when it dries it has a smooth, shiny appearance. Hot water has the opposite effect, creating frizz and drying out your hair. Sulfates are found in many cleansers, including dishwashing detergent, laundry detergent, and more. Sulfates are effective and washing away oil and grease, but using this ingredient on your hair can be too harsh, causing frizz and damage to your hair. Look for sulfate-free shampoo that will cleanse your hair without stripping away its protective oils. Conditioner helps hair stay smooth and silky by moisturizing it and keeping it tangle-free. Look for a conditioner that will keep your hair smooth without weighing it down. Silicone-free conditioner is best, since silicones build up in your hair and cause it to look dull after a while. Opt for a product that has glycerin in it, instead. Trimming off the dry, coarse ends of your hair will keep it looking lighter, smoother, and softer. Aim to get regular trims to remove split or damaged ends. You don’t need to hack a ton of hair off each time, simply trimming 1 inch (2.5 cm) or so should do the trick. Cotton pillowcases can absorb moisture from your hair, leaving it dry and dull. Swap out your pillowcase for silk one, or wrap your tresses in a silk scarf before going to bed. Your hair will be smooth and silky in the morning.
Question: What is a summary of what this article is about?
a few times a week instead of every day. Use cold water when you wash and rinse your hair. Use sulfate-free shampoo. Opt for a moisturizing conditioner. Trim your tresses every 6-12 weeks. Sleep on a silk pillowcase or use a silk scarf at night.

Article: A couch is a big investment, and ordering it sight unseen is a big risk. Deciding whether a couch is to your exact taste and can stand the test of time is almost impossible to do with pictures alone.  That being said, online reviews are helpful for learning other people’s thoughts on the comfort and durability of potential couches. Make sure you are comfortable with the return policy of the couch distributor and the quality of customer support you’re likely to get if you experience troubles with your purchase.  You may have to pay shipping if you order online, and will probably need to be present when the couch is delivered. Contact the couch company immediately if you find any problems. Sit how you normally would on the couch, then see how you feel. Different couches have different softness, and factors like seat depth and armrest height make a difference, too. Lower arms are good for curling up and getting comfy while watching TV, while multi-cushion sofas might be harder to nap on and firm seat backs are more supportive if you usually sit upright. Swaying, creaking, or squeaking indicate poorly installed springs or a weak frame. Lift one side about 6 in (15 cm) off the ground. If the leg on the other side is still touching the ground, the frame is weak. The couch legs should be attached to the frame by screws and pegs, not just glue, staples, and nails. They should be tight and close together, but not feel like they are poking through the fabric. If the sofa has only webbing or mesh, it will probably be uncomfortable and flimsy. Feel free to ask the salesperson for a swatch of the upholstery to bring home, where you can see how the fabric looks in artificial and natural light and test how easy it is to clean.  Cotton and linen upholstery is reasonably priced and easy to clean, and microfiber blends can act like cotton and are stain resistant. Leather looks nice and lasts a long time, but is extremely expensive. Natural blends with polyester can snag and wear out overtime. Silk gives the couch a sleek look but is very hard to care for. The average couch sells for $1,000 but designer couches can cost $10,000. The couch should compliment the space you are going to put it in, and feel like a piece you’ll want in your home for many years to come. Discuss the price for delivery up front, and make sure you can get a full refund if the store doesn’t deliver on time.
Question: What is a summary of what this article is about?
Test the couch in person, even if you plan to order it online. See how comfortable you find the couch. Assess the sturdiness of the frame. Press the springs through the upholstery, if there are any. Experiment with lighting and by staining the couch fabric. Buy your couch or sofa.
