Eureka lemons, botanically classified as citrus lemons, are an acidic variety belonging to the Rutaceae family. With its vibrant yellow hue and tangy aroma, Eureka Lemon is a timeless citrus classic. Known for its versatility in culinary and non-culinary applications, Eureka lemons have become a staple in households around the world. It is an Italian lemon variety developed in Los Angeles in the mid-19th century. Eureka lemons are highly regarded for their aromatic, oily rind, balanced sweet and spicy flavor, and consistency in size and appearance. This variety is often nicknamed the "four-season lemon" by California growers because the tree produces a variety of crops year-round and has a thick skin that allows the fruit to be transported long distances without damage. Modern times, the Eureka lemon is one of the two main lemon varieties grown commercially in the United States.
Origin and characteristics:
California roots:
The word Eureka is derived from the Greek word "heureka" which means "I found it". There are several antidote stories about how this Greek word became a popular expression, the most famous of which centers on the famous Greek mathematician Archimedes. While none of these stories have confirmed sources to support that these are real events, legend has it that Archimedes exclaimed, "Heureka! Heureka!" when he discovered a way to determine the purity of gold. Centuries later, "eureka" was used to express surprise and sudden discovery during the California Gold Rush of 1848. The exclamation eventually became California's motto in 1963 and was featured on the state seal in 1849 to commemorate the Gold Rush. Around the same time in the late 1800s, the Eureka lemon was given this nickname because the variety was a surprising discovery to California growers and was initially named Gary's Eureka and later simply Eureka. Rika.
The Eureka Lemon was developed in Los Angeles, California in 1858. Experts believe the Eureka lemon is a descendant of the Lunario lemon introduced from Italy in the early 1800s. The seeds were sown in 1858, and a few years later breeders CR Workman and Andrew Boyle selected the most promising seedlings from the group for commercial planting. Selected seedlings were propagated, and in 1877 Workman gave lemon scions to Thomas A. Garey, a prominent Los Angeles nurseryman, to be grafted onto rootstock in his nursery. Garey named the fruit Garey's Eureka, and the variety was favored by growers for its perennial, prolific and thornless qualities. After the Eureka lemon hit the market, it quickly spread throughout California's citrus growing regions and remains one of the most prolific lemons in the state. Today, Eureka lemons are commonly found in local markets, grocery stores, and dealers, and are often grown in home gardens. Eureka lemons are grown in the United States, Israel, Australia, South Africa and Argentina.

The Eureka lemon is a medium to large variety, with an average diameter of 5 to 6 cm, and is rectangular to oval in shape, bulbous and rounded, tapering at both ends in the center.

The lemon peel is of medium thickness, tightly attached to the pulp, and covered with sunken oil glands, giving the surface a slightly rough texture.

Beneath the surface, the pulp is surrounded by a bitter, white, spongy pith and is divided into 8 to 10 parts by a thin membrane. The yellow-green flesh is soft, watery, tender, mostly seedless or contains a few cream-colored, teardrop-shaped seeds. Eureka lemons contain volatile aromatic oils that are released through the peel, creating a bright, sweet and refreshing scent.
