This buying guide aims to provide a comprehensive overview of nasturtium, focusing on its acquisition, quality assessment, and practical uses. By understanding the nuances of buying nasturtium, you can elevate your culinary endeavors and make informed choices for your kitchen.

What Is Buying?

Buying, in the context of food ingredients, refers to the process of selecting and procuring specific items for culinary use. This encompasses understanding the quality, availability, and pricing of the ingredient while considering its applications in various dishes. For nasturtium, buying entails recognizing its diverse varieties, assessing freshness, and ensuring that you are sourcing it from reputable suppliers, whether you are a chef, a home cook, or a food enthusiast.

History and Origins

The history of nasturtium can be traced back to the ancient civilizations of South America, particularly Peru. The plant was revered not only for its culinary uses but also for its medicinal properties. European explorers brought nasturtium back to Europe in the 16th century, where it quickly gained popularity. Its name derives from the Latin words “nasus” (nose) and “tortus” (twisted), referring to the flower’s pungent aroma, reminiscent of a mustard-like flavor.

Over time, nasturtium has been cultivated for various purposes, including ornamental gardening and as a companion plant in agriculture. Its resilience and ability to thrive in diverse conditions have made it a staple in gardens around the world, allowing it to evolve into numerous varieties.

Production and Processing

Nasturtium is primarily grown in temperate climates, thriving in well-drained soil and full sunlight. It is typically cultivated from seeds, which can be sown directly into the ground or started indoors. The plant is known for its rapid growth, reaching maturity within 60 to 70 days. It can be harvested continuously throughout the growing season, with flowers and leaves available for use.

Once harvested, nasturtium is often sold fresh, dried, or as seeds. Fresh nasturtium should be handled delicately to preserve its vibrant color and crisp texture. When dried, it retains some of its flavor but loses its visual appeal, making fresh varieties preferable for culinary applications.

Quality and Grading

The quality of nasturtium is determined by several factors, including freshness, color, and flavor. When purchasing, look for:

  • Freshness: The leaves and flowers should be crisp and vivid in color. Wilted or discolored specimens indicate age and diminished quality.
  • Size: The size of nasturtium blooms can vary. Smaller flowers are often more concentrated in flavor, while larger ones may be milder.
  • Variety: Different varieties, such as Tropaeolum majus, offer unique flavors and colors. Familiarize yourself with the specific type you desire for your culinary use.

    • Grading systems are not universally applied to nasturtium, as it is often sold in bulk or as a unique product. However, reputable suppliers will ensure that their offerings meet high standards of quality.

    Buying Considerations

    When buying nasturtium, several factors should be taken into account to ensure you are making the best choice:

    1. Source: Consider purchasing from local farmers’ markets, specialty grocery stores, or organic suppliers. These sources often provide fresher products compared to larger retailers.

    2. Seasonality: Nasturtium is typically in season from late spring to early fall. Buying in-season not only guarantees better quality but also supports local agriculture.

    3. Organic vs. Conventional: If pesticide use is a concern, opt for organic nasturtium. Organic farming practices not only promote environmental sustainability but also enhance the flavor profile of the plants.

    4. Varietal Differences: Familiarize yourself with the various types of nasturtium. Some are better suited for salads, while others may be ideal for garnishing or infusing flavors in oils.

    5. Storage Options: Plan your purchase according to your intended use. If you plan to use it immediately, fresh nasturtium is ideal. For longer storage, consider dried options or even growing your own plants.

    Uses and Applications

    Nasturtium is a versatile ingredient that can be employed in a multitude of culinary applications:

  • Salads: The vibrant flowers and peppery leaves add visual appeal and a burst of flavor to salads.
  • Garnishes: Use nasturtium flowers as a striking garnish for various dishes, from appetizers to main courses.
  • Infusions: Nasturtium can be used to infuse oils or vinegars, adding a unique flavor to dressings and marinades.
  • Stuffed Dishes: The large leaves can be used as wraps for various fillings, offering a delightful taste and texture.
  • Herbal Blends: Dried nasturtium can be ground into powder and mixed with other herbs for seasoning.

Storage and Shelf Life

Fresh nasturtium should be stored in the refrigerator, preferably in a breathable container like a paper bag or wrapped in a damp paper towel. This helps maintain its crispness and flavor. Under ideal conditions, fresh nasturtium can last for about a week.

Dried nasturtium should be stored in an airtight container in a cool, dark place. When properly stored, dried nasturtium can retain its flavor for several months, though it is advisable to use it within six months for optimal taste.
