Nasturtiums, with their bold, peppery flavor and vibrant, sun-kissed blooms, are more than just a pretty face in the garden. These cheerful flowers have a long history of culinary use, bringing both visual appeal and a unique taste to dishes. But the burning question for many gardeners and food enthusiasts is: can you actually eat nasturtiums? The answer is a resounding yes, and the culinary possibilities are surprisingly diverse. From the peppery petals to the tangy seeds, nasturtiums offer a delightful and nutritious edible option for those willing to explore beyond traditional vegetables.
The Edible Appeal of Nasturtiums: Flavor Profile and Culinary Uses
Nasturtiums (Tropaeolum majus) are prized for their distinctive flavor, which is often described as peppery, spicy, and slightly mustard-like. This characteristic comes from the presence of glucosinolates, the same compounds responsible for the pungency of mustard, radish, and horseradish. The intensity of this flavor can vary depending on the specific variety and even the growing conditions. Some varieties offer a milder, more subtle peppery note, while others pack a more potent punch. This range makes them versatile in the kitchen, allowing you to tailor their use to your preference.
The most commonly consumed parts of the nasturtium plant are its:
Flowers: These are perhaps the most visually striking edible component. Their bright orange, yellow, red, and sometimes even pink hues can instantly elevate the presentation of any dish. The petals have a tender texture and a pronounced peppery flavor that works wonderfully in salads, as garnishes for appetizers and main courses, or even stuffed.
Leaves: The broad, shield-shaped leaves also contribute to the edible bounty of the nasturtium. They possess a similar peppery taste to the flowers, though often with a slightly more herbaceous undertone. Young, tender leaves are best, offering a pleasant crunch and zest when added to salads, sandwiches, or used as a wrap. Mature leaves can be a bit tougher and more intensely flavored, making them suitable for cooking, similar to how one might use spinach or collard greens.
Seeds (Pods): Unripe nasturtium seed pods, often referred to as “Poor Man’s Caper” or “Nasturtium Capers,” are a particularly interesting and unique edible part of the plant. When pickled, these green, button-like pods develop a briny, caper-like flavor and a firm texture. They are an excellent substitute for traditional capers and can add a delightful zing to dressings, sauces, fish dishes, and pasta. Even the mature seeds can be dried, roasted, and ground into a peppery spice, although this is less common.
Incorporating Nasturtiums into Your Diet
The beauty of nasturtiums lies in their adaptability. Their vibrant colors and distinctive flavors make them a welcome addition to a wide range of culinary creations.
Salads and Greens
Perhaps the simplest and most popular way to enjoy nasturtiums is in salads. Scatter a handful of brightly colored petals and young leaves over your favorite green mix for an instant burst of flavor and visual appeal. They pair exceptionally well with milder greens like lettuce, spinach, and arugula, providing a contrasting peppery note that cuts through richness. Try them in a simple vinaigrette-based salad or incorporate them into more complex creations with fruits like berries or apples, nuts, and cheese.
Garnishes and Appetizers
Nasturtium flowers are fantastic for garnishing. Place a few blooms atop canapés, bruschetta, or deviled eggs for an elegant and edible decoration. Their peppery kick can also complement creamy dips or savory spreads. Consider stuffing nasturtium flowers with a light cheese filling, such as cream cheese or ricotta mixed with herbs, for an impressive appetizer.
Main Courses and Side Dishes
Beyond salads, nasturtiums can add an interesting dimension to main courses. Chopped leaves can be stirred into pasta dishes, stir-fries, or omelets. Their peppery flavor can also be a welcome addition to pesto, offering a spicier alternative to basil. When cooked, nasturtium leaves can become milder, making them suitable for sautés or incorporated into savory tarts and quiches.
Pickled Nasturtium Seeds (Capers)
The preparation of nasturtium seeds as capers is a culinary art form in itself. The unripe seed pods are typically harvested when they are still firm and green. They are then brined in a mixture of vinegar, water, salt, and sometimes spices like peppercorns, dill, or garlic. After a period of pickling, these “nasturtium capers” develop a tangy, briny flavor that closely resembles traditional capers, making them a delightful addition to a variety of dishes.
Nutritional Benefits of Eating Nasturtiums
Beyond their culinary appeal, nasturtiums also offer a surprising array of nutritional benefits. While not a staple food, incorporating them into your diet can contribute to your intake of important vitamins and minerals.
Nasturtiums are known to be a good source of:
Vitamin C: This essential antioxidant plays a crucial role in immune function, skin health, and collagen production.
Vitamin A: Important for vision, cell growth, and immune function.
Minerals: They also contain trace amounts of minerals like iron, potassium, and manganese.
The glucosinolates present in nasturtiums, which contribute to their peppery flavor, are also believed to have potential health-promoting properties. Research suggests that glucosinolates and their breakdown products, such as isothiocyanates, may possess antioxidant, anti-inflammatory, and even anti-cancer properties. However, more research is needed to fully understand these potential benefits in humans.
Growing Your Own Edible Nasturtiums
Cultivating nasturtiums is a rewarding experience for any gardener, especially when you know that the fruits of your labor are also edible. These plants are remarkably easy to grow, making them an excellent choice for beginners.
Here are some key aspects of growing edible nasturtiums:
Sunlight: Nasturtiums thrive in full sun but can tolerate partial shade. More sun generally leads to more flowers.
Soil: They prefer well-draining soil and are not particularly fussy about soil type. In fact, overly rich soil can lead to abundant foliage at the expense of flowers.
Watering: Water regularly, especially during dry periods, but avoid waterlogging.
Planting: Nasturtiums can be sown directly into the ground after the last frost or started indoors a few weeks prior. They are fast-growing and will readily produce blooms and seeds throughout the summer and into the fall.
Varieties: There are numerous nasturtium varieties to choose from, each with slightly different growth habits and flower colors. Some common types include trailing varieties, which are perfect for hanging baskets or spilling over walls, and bush varieties, which are more compact. Popular edible varieties known for their abundant blooms and palatable leaves include ‘Alaska’ (with variegated foliage), ‘Jewel Mix’ (a blend of colors), and ‘Cherry Rose’ (for its vibrant pink flowers).
Pest and Disease: Nasturtiums are generally quite resistant to pests and diseases. However, they can sometimes be susceptible to aphids. Companion planting with nasturtiums can actually help deter certain pests from other vegetables in your garden.
Harvesting and Storing Your Edible Nasturtiums
To enjoy the full culinary potential of your nasturtiums, proper harvesting techniques are essential.
Flowers: Harvest nasturtium flowers in the morning after the dew has dried. Gently pinch or snip the flower from the stem, taking care not to bruise the delicate petals. For the best flavor and appearance, pick them just as they open.
Leaves: Young, tender leaves are best for salads and raw consumption. Harvest them from the outer part of the plant. Mature leaves can be picked for cooking.
Seeds: Harvest the unripe seed pods when they are firm and green. These are typically picked before they start to swell and turn brown. If you wish to harvest mature seeds for grinding, wait until the pods have dried on the plant.
Storage of nasturtiums is best done shortly before use, as they are quite delicate.
Flowers and Leaves: For short-term storage, place freshly harvested flowers and leaves in a loosely sealed container or bag with a damp paper towel in the refrigerator. They will generally keep for a few days.
Seeds: Pickled nasturtium seeds can be stored in airtight jars in the refrigerator for several months. Dried seeds should be stored in a cool, dry place.
Safety Considerations When Eating Nasturtiums
While nasturtiums are generally safe to eat and widely enjoyed, it’s always important to be mindful of a few considerations:
Pesticide-Free: Ensure that any nasturtiums you plan to consume have been grown without the use of pesticides or other harmful chemicals. If you are not growing them yourself, purchase them from a reputable source that can guarantee they are edible grade.
Identification: Always be absolutely certain of your plant identification before consuming any part of it. While nasturtiums are distinctive, misidentification can lead to serious health consequences.
Allergies: As with any food, there is a possibility of allergic reactions. If you have known sensitivities to plants in the Brassicaceae family (like mustard or radish), you might want to approach nasturtiums with caution or test a small amount first.
Pregnancy and Breastfeeding: While there is no widespread scientific consensus on the safety of consuming nasturtiums during pregnancy or breastfeeding, it is generally advisable for pregnant and breastfeeding individuals to err on the side of caution and consult with a healthcare professional before incorporating new and unfamiliar foods into their diet.
