Lemon: Unraveling the Fruit or Vegetable Conundrum

Is lemon a fruit or a vegetable?

Lemons are a popular citrus fruit commonly found in supermarkets. However, there has been some confusion as to whether lemons should be classified as a fruit or a vegetable. In this article, we will look at the botanical features and characteristics of lemons to determine their proper classification.

How to distinguish between fruits and vegetables

Before we can determine whether lemons are fruits or vegetables, it is important to understand the defining characteristics of each category.

Seeds or no seeds?

A key distinction between fruits and vegetables is the presence of seeds. Fruits are the result of reproductive processes in flowers and contain seeds, while vegetables, such as leaves or roots, do not produce seeds.


While taste is not a determining factor in classifying an item as a fruit or vegetable, it can provide some insight. Fruits often have a wide range of tastes, including sweet, sour, bitter, or tartness. Vegetables, on the other hand, typically have distinct flavors that are not easily categorized.

Food & Nutrition

Fruits and vegetables share similarities in their nutritional composition. They are generally low in fat and high in fiber. However, fruits tend to have higher sugar content, while only certain starchy vegetables contain significant amounts of sugar.

What makes a lemon a fruit?

Now that we have a basic understanding of the differences between fruits and vegetables, let’s explore why lemons are classified as fruits.

Lemons contain seeds

A clear indication that lemons are fruits is the presence of seeds. When a lemon is cut open, it reveals numerous seeds within its structure. This is consistent with the botanical definition of a fruit as the ovary of a plant that produces seeds.

Lemons are a hybrid of other fruits.

Lemons are not naturally occurring fruits, but rather a man-made hybrid of two citrus fruits: the bitter orange and the citron. This hybridization process resulted in the creation of a new fruit that we now know as the lemon. The fact that lemons are derived from other fruits further supports their classification as a fruit.

Lemons grow from flowers

Observing lemon plants in a farm environment reveals the presence of beautiful white flowers. These flowers serve as the plant’s reproductive organs, and it is from these flowers that lemons develop. If lemons were vegetables, they would grow from other parts of the plant, such as leaves or roots. The fact that lemons grow from flowers solidifies their classification as fruits.

Is a lemon a berry?

Surprisingly, lemons are classified as berries as well as fruits. In botanical terms, a berry is a fleshy fruit consisting of three distinct layers: the exocarp (outer layer), the mesocarp (fleshy middle layer), and the endocarp (inner layer containing the seeds). In addition, the berries must contain more than two seeds. Lemons meet all of these criteria, making them both fruits and berries.

What to do with lemons

Because lemons are fruits, they are commonly used in various culinary preparations, especially desserts. Here are some popular lemon-based desserts:

1. 3 Ingredient Lemon Cake

A simple yet delicious dessert, 3 Ingredient Lemon Pie requires only three basic ingredients. It is a quick and easy way to satisfy your lemony sweet tooth.

2. Lemon Marmalade

Lemon marmalade is a fruit preserve made from lemons. By combining lemon pulp and peel with sugar and water, you can make a fresh batch of tangy marmalade at home. The process involves boiling the ingredients until they are well mixed and then allowing the marmalade to cool.

3. Lemon Sorbet

Lemon sorbet is a refreshing frozen dessert made from lemons. Its sweet and tangy flavor makes it a perfect treat, especially during the summer months. Lemon sorbet can be enjoyed on its own or as a palate cleanser between courses.

4. Lemon Cake

Lemon dump cake is a popular bakery item with lemon as the main ingredient. Despite the acidity of lemons, they pair well with baked goods, adding a fruity and refreshing element to cakes, pies, muffins and tarts.

5. Lemon Candy

The sour and bitter taste of lemons makes them a popular choice for fruit-flavored candies. Their refreshing and cooling effect enhances the sweetness of the candies, creating a delightful flavor combination.
