Rocket cress, also known as arugula, is a leafy green vegetable with a peppery taste commonly used in salads and other dishes. Its popularity has led to the creation of many synonyms such as salad rocket, roquette, rugula, and Italian cress. These synonyms all refer to the same plant but are used interchangeably depending on the region or personal preference. In Northern Europe, it is known as roquette, while it is referred to as rucola in Italy and arugula in America. Regardless of its name, it is a delicious and nutritious addition to any dish.
