Lemon juice and lemon are two closely related foods, but they are not the same. Both foods have a sour, acidic taste. However, lemon is a whole fruit including peel, seeds, and pulp. Lemon juice is only the juice extracted from the lemon fruit and does not contain peel or seeds, though it may contain pulp. Extracting lemon juice from lemon is not challenging, but buying pre-made lemon juice from a grocery store may be more convenient.
While the consistencies and textures of lemon juice and lemon are different (one is solid and one is liquid), the flavor is the same.

Lemon Juice Explained
Lemon juice has a tangy and sharp flavor and has many uses, such as making drinks or cocktails and adding flavor to salads, meat dishes, and desserts like lemon bars. Lemon juice ingredients depend on whether the juice is freshly squeezed or store-bought.
Freshly squeezed lemon juice contains only lemon and may contain some pulp and seeds if it hasn’t been strained. The juice is squeezed from the fruit, and the seeds are removed. Most people like to remove the pulp as well, by straining or using a special juicing device.
Store-bought lemon juice may contain water, lemon oil, and preservatives, depending on the company that produced it.
Uses
Lemon juice has many uses, particularly for marinades, in drinks like lemonade, or for baking or cooking meals such as lemon chicken or lemon cake. It’s also used to flavor meats like chicken, beef steak, and shrimp. It may also be used as a salad dressing to add a sharp, citrus flavor.
In beverages, lemon juice is ideal for making lemonade and other drinks like lemon drop cocktails. As a baking ingredient, lemon juice provides a great sharp and tangy taste and can also be used in jams to help the jam set properly.

Both lemons and lemon juice have many uses in cooking, baking, flavoring, and making drinks. While lemon juice is used often in drinks and cooking to help flavor foods like meat, lemons are usually used more sparingly, in small quantities, due to their sharp, acidic taste. For instance, lemon wedges are often used simply as a garnish.
Sometimes using lemon or lemon juice depends purely on preference. It may also depend on what the recipe calls for. The two ingredients can be used interchangeably in many dishes. For instance, lemon water can be made by adding lemon juice to the water or slices of lemon, depending on preference.
Lemon bars can also be made using either lemons or lemon juice. You can even use yuzu, which is a Japanese lemon, for a stronger flavor. And some lemon chicken recipes call for lemon juice, but you can garnish with sliced lemons or sliced yuzu. When choosing between lemon and lemon juice, consider what the recipe calls for and how much sourness and acidity you prefer.
