Problem: Article: Pour 1/2 cup (125 ml) of milk into a medium mixing bowl. Add the egg yolks and cornstarch to the same bowl and whisk well. Continue whisking until the mixture seems smooth and the contents are evenly distributed. Pour the remaining milk in a medium saucepan. Add the lemon zest, sugar, cinnamon stick, and salt to the same saucepan, then set the pan on your stove over medium-low heat. Mix the contents of the saucepan slowly and continuously as they heat up and do not use a higher heat setting. Milk burns and sticks to pans easily, so continuous motion and low heat are both necessities. Continue heating and stirring until the mixture becomes hot but do not allow it to reach a boil yet. This step should take several minutes. Slowly pour the egg yolk mixture into the hot milk mixture, mixing the two together constantly to combine them. Continue stirring and heating the mixture over medium-low heat until it boils. After it begins to boil, continue whisking it for 2 minutes or longer. Test the taste of the natillas after the first 2 minutes. If you can detect the taste of cornstarch, you'll need to continue heating the mixture for another minute or so. If the cornstarch taste is gone, you can proceed to the next step. Remove the saucepan from the stove. Take out the lemon zest and cinnamon stick, then add the vanilla extract, stirring it in until evenly distributed. In a separate bowl, beat the egg whites using an electric mixer set to low speed, continuing until stiff peaks form. When the egg whites are ready, stiff peaks should form when you lift the mixer out. These peaks should stand sharply without drooping. Note that the addition of egg whites is mostly found in Mexican versions of natillas. Many traditional Spanish versions do not use egg whites, and the result is a much denser custard. As such, you may omit the egg whites altogether if desired. Top the custard in your saucepan with the stiff egg whites. Carefully fold the egg white into the custard with a spatula until no visible streaks of white remain. Fold carefully, applying as little pressure as possible to the egg whites during the process. Working too quickly or with too much force can cause the egg whites to lose most of the air you just beat into them. Carefully press a sheet of plastic wrap over the surface of the natillas, then place the saucepan in your refrigerator until the custard is cool and semi-set. If you want to serve the natillas in individual custard cups, you should pour the mixture into the cups while it is still warm. After the natillas have cooled and set, scoop the custard into individual serving dishes and sprinkle each one with ground cinnamon or ground nutmeg. Alternatively, you could top each helping of natillas with a shortbread cookie. You should be able to store natillas in sealed containers for 3 days inside your refrigerator.
Summary: Combine 1/2 cup (125 ml) milk with the egg yolks and cornstarch. Mix together the seasonings and remaining milk. Add the egg yolk mixture. Heat until the mixture boils. Add the vanilla but remove the cinnamon and lemon. Beat the egg whites until stiff peaks form. Fold the egg whites into the custard. Chill for a minimum of 3 hours. Serve when ready.

Problem: Article: Many online perfume retailers offer free samples when you purchase from their store. Choose a perfume and place it in your online cart. As you checkout, you will be prompted to choose free samples. Some retailers will offer only perfume and cologne samples. Other retailers will offer samples of perfume and other beauty products. Choose the samples you want and they will be automatically added to your cart. Some places require you to spend a certain amount to be eligible for free samples. For other stores, you must buy something from the beauty department. For example, you couldn't buy a dress and qualify for free perfume samples. Online retailers that offer free perfume samples include Sephora, Macy's, Ulta, and Nordstrom. Many perfume manufacturers will send e-mail offers for free samples of new and upcoming scents to people on their mailing list. Decide which perfume companies you like and want to receive samples from, and then sign up for their mailing lists. Make sure to look for offers when you know new perfumes are coming out. This can be time consuming and may yield little rewards. Many companies will have limited amounts of samples, so you have to make sure you check at the right times. Get a separate e-mail address for this. That keeps spam from your regular e-mail. Some companies you may want to sign up with are Hermes, Burberry, Calvin Klein, Marc Jacobs, Ralph Lauren, and Dolce and Gabana. Browse perfume catalogs and the perfume counter to get ideas for companies to sign up with. Instead of waiting for a new fragrance to come out, try to get a sample now. Write the perfume manufacturer's customer service and ask them for free samples. Make sure to be polite. Don't be offended or upset when they say no. Some companies will send you a sample; others will not. There are websites that collect free online offers, like free samples. They find them through the manufacturer's websites, Facebook, and other offers. They will send e-mails with daily or weekly offers, or post them on their website. Use an alternate e-mail address. Don't use your primary address. You don't want to end up with a lot of spam. Don't give out your credit card information. These sites should send you to free samples, not places where you have to buy things. The same goes for shipping costs. Also don't get tricked into buying products for the samples through these websites.
Summary: Order from perfume retailers. Sign up with the perfume company. Contact customer service directly. Sign up for free sample websites.
