Hi! I'm Lemon!
“I just love the sun, don't you? That's because I'm a lemon, and we grow so much better in sun and warmth. My skin is a lovely, sunny yellow color. I'm a citrus fruit, but I'm not sweet like an orange. So if you bite into me, your mouth might pucker! But if you squeeze out my juice, then add water and sugar to it, you'll enjoy the sweet and sour taste of lemonade! My zest and juice can bring a wonderful brightness to many dishes."
History
- Lemon trees are small evergreen trees thought to be native to Asia. Sometime in the first century, they came to Italy and the Mediterranean region. Although the trees were widely distributed throughout the Middle East and Mediterranean countries between the 8th and 11th centuries, they weren't cultivated to a great extent until the middle of the 1400s in Italy. Spanish explorers brought lemon seeds with them to the Americas later in the 15th century. By the 19th century, you could find lemon trees in Florida and California.
- Today, California and Arizona produce 95 percent of the entire lemon crop in the United States.
- During the European Renaissance, fashionable ladies used lemon juice as a way to redden their lips! Today you might find people with naturally blond or light brown hair using lemon juice, diluted with water, to lighten their hair. This method is subtle and requires exposure to sunlight to see results, so be sure to put sunscreen on your skin!
- Lemons were once so rare that kings would give them away as gifts.
Anatomy & Etymology
- There are two different types of lemons—acidic and sweet. The most common acidic varieties include Eurekas and Lisbons. The acidic types are grown commercially, and the sweet types are grown mainly by home gardeners. Lemon trees bloom and produce fruit year-round. Each tree can produce up to 500 to 600 lemons annually.
- Lemons are hybrids of bitter or sour oranges and citrons, another type of citrus fruit.
- Lemons are technically berries. All citrus fruits are berries!
- Lemons are protected by a rind or peel and a lining of spongy, white tissue called the "pith." When zesting lemon peel for a recipe, you want to avoid including the pith, which is bitter. Lemon flesh is plump, full of juice, and studded with seeds.
- Common types of lemons include Eureka, Lisbon, and Meyer. Meyer lemons have a sweeter, more floral taste and aroma. They are a combination of a lemon and a sweet orange. Eureka lemons are the most prolifically grown lemon in the world. They have pointed, tapered ends.
- The word "lemon" is from the Middle English "lymon," from the Old French "limon," which is from the Arabic "līmūn," a collective term for citrus fruits.
How to Pick, Buy, & Eat
- To choose lemons with the most juice, look for those with thin peels and are heavy for their size. There are about three tablespoons of lemon juice in one lemon and about eight seeds.
- Lemon juice is sour by itself, but you can add lemon juice and zest from the rind to bring an acidic balance to a sweeter recipe, like cakes, cookies, and curds. It also brightens up vinaigrettes, marinades, and risottos. Lemons can be squeezed over grilled, fried, or roasted chicken, fish, or vegetables. You can make lemonade with the juice and tea from the lemon leaves.
- Lemon juice keeps cut pears, apples, bananas, and avocados from turning brown because the acid helps keep the fruit from oxidizing.
Nutrition
- Vitamin C! The rind of the lemon has the most vitamin C. Since lemons are high in vitamin C, they have been used throughout history to prevent scurvy—a disease that causes bleeding gums, loose teeth, and aching joints. To this day, the British Navy requires ships to carry enough lemons so that every sailor can have one ounce of lemon juice a day. The demand for lemons and their scurvy-preventing properties hit a peak during the California Gold Rush of 1849. Miners were willing to pay large sums for a single lemon. As a result, lemon trees were planted in abundance throughout California.
- Lemon oil, extracted from lemon peel, cannot be ingested. However, when diluted and applied to a person's skin, there is evidence that it acts as an antibacterial and antifungal. Diffused in the air or added to bath water as aromatherapy, it can ease anxiety and stress, lift mood, and sharpen brain function.
- Citrus fruits, like lemons and limes, have citric acid, which can help prevent kidney stones from forming.
What is Streusel?

- "Streusel" (German pronunciation: STROY-zel) means "something scattered or sprinkled" in German. In American English, it is pronounced STROO-sel. Traditionally, streusel is a sweet crumb topping. It can also refer to a cake or pastry with a streusel topping.
- Streusel originated in Germany sometime in the 17th century. The crumb topping was added to a yeast cake called "streuselkuchen" (streusel cake), which was a popular dessert for special occasions. German immigrants to the United States brought their crumb cake recipes with them.
- The main ingredients for the crumb topping are sugar, butter, and flour, and their ratio is about one part sugar, one part butter, and two parts flour. Other possible ingredients include oats, nuts, and cinnamon or other spices.
- A savory streusel topping may replace the sugar with bread crumbs, cheese, salt, spices, or grated or minced vegetables. A savory streusel might be good on savory pies, macaroni and cheese or other casseroles, salads, soups, and vegetable dishes.
- A sweet streusel can top cakes, doughnuts, fruit crisps, ice cream, muffins, pies, and quick breads.
Let's Learn About Germany!

- The central European country of Germany, officially the Federal Republic of Germany, is known as "Deutschland" (DOYCH-lunt) in the German language. It is a federal parliamentary republic with a president, a chancellor (the head of the government), and a legislature.
- Germany has over 83 million people in an area of 137,847 square miles, a little smaller than the U.S. state of Montana.
- The capital and largest city in Germany is Berlin, but only since 1990 when East and West Germany reunified. Before that, East and West Germany were divided by the Berlin Wall, built after World War II to keep Eastern citizens from fleeing to the West. The Berlin Wall kept the two sides of Germany separated for 28 years. The wall finally crumbled in November 1989, and you can see segments of the original wall in many places in Germany and other countries.
- Germany was the first country in the world to adopt Daylight Savings Time. This was done in 1916 during World War I to conserve fuel.
- Football (soccer) is the most popular sport in Germany, and the German Football Association is the largest single-sport league worldwide. Motorsports are also big in Germany, with three well-known German carmakers heavily involved, BMW, Mercedes, and Porsche.
- Hamburg, Germany, has the most bridges in the world. The city has more than 2,300 bridges!
- In Germany, undergraduate university education is free, even to international students. Although a few programs are taught in both English and German, a student would need a firm knowledge of the German language to attend most universities. Germany also has a vocational education system that combines learning with company apprenticeships.
- Germany is known for its sausages, and some, like "bratwursts" or "brats," are popular in the United States. Over 850 million "currywursts" (curry sausages sold on the street) are eaten in Germany per year! Bread, cheese, and beer are also significant parts of German cuisine.
- During World War II, Coca-Cola syrup could not come into the country due to a US trade embargo with Nazi Germany. This resulted in the company's German division inventing Fanta soda, what we now know as an orange soda. However, the modern version was developed in Italy in the 1950s. They initially made the early German version with whey (the liquid left after making cheese), apple pomace (the pulp left from making apple juice), and beet sugar.
- The Autobahn is a famous access highway in Germany. It is over 8,000 miles long, and many parts have no enforceable speed limit. People travel from around the world to drive fast cars on the Autobahn. It's illegal to run out of gas on this highway!
What's It Like to Be a Kid in Germany?
- In Germany, often both parents work, and every child under three can go to daycare. Kids can start kindergarten from 3 to 5 years old.
- On the first day of first grade, parents give their children a giant cone filled with toys, candy, and school supplies. The school cone is called a "schultüte," celebrating an important rite of passage in their young lives.
- Popular sports for youth include football (soccer), handball, and gymnastics. Kids primarily participate in a sport through a sports club, and there are thousands of sports clubs in Germany for almost every sport.
- German kids can visit one of the biggest zoos in the world, the Zoologischer Garten Berlin (Berlin Zoological Garden). Although its size isn't the largest, it houses the most animal species worldwide. The zoo opened in 1844 and its aquarium in 1913.
- There are several amusement and theme parks in Germany, and if kids are familiar with stories from the Brothers Grimm, families can drive the German Fairy Tale Route (Deutsche Märchenstraße) that runs 370 miles. The route passes through scenic nature parks and charming villages, and several places on the way relate to the fairy tales, such as Little Red Riding Hood's house, Sleeping Beauty's castle, and the Pied Piper's town of Hamelin. Speaking of castles, you can also visit the Neuschwanstein Castle in the Bavarian Alps, which may have inspired Disneyland's Sleeping Beauty Castle.
