Nasturtium Butter: A Chef’s Ode to Peppery Sunshine

The first time I tasted nasturtium, I was a young apprentice, foraging in the chef’s garden behind the restaurant. I popped a vibrant orange flower into my mouth, expecting sweetness, and was surprised by a burst of peppery heat. It was unlike anything I’d tasted before, a flavor that lingered, hinting at summer days and culinary possibilities. From that moment, I was hooked, always looking for new ways to incorporate these edible jewels into my dishes. This nasturtium butter is a tribute to that initial discovery, a simple yet elegant way to capture the flower’s unique essence.

Recipe Overview

• Prep Time: 5 minutes
• Yields: 1 pound
• Dietary Type: Vegetarian, Gluten-Free

Ingredients

• 1 lb butter, softened (high-quality, unsalted butter is recommended for the best flavor)
• 1 quart nasturtium blossoms (freshly picked, rinsed, and gently dried)
• Juice of 1 lemon (freshly squeezed)

Equipment Needed

• Food processor or blender
• Airtight container for storage

Instructions

1. Ensure your butter is properly softened. This is crucial for achieving a smooth, consistent texture. If it’s too hard, it will be difficult to blend, and if it’s melted, the butter may separate. Allow it to sit at room temperature for at least an hour, or until it yields easily to gentle pressure.
2. Thoroughly rinse the nasturtium blossoms under cold water to remove any dirt or insects. Gently pat them dry with a clean kitchen towel or paper towels. This will prevent the butter from becoming watery.
3. In a food processor or blender, combine the softened butter, nasturtium blossoms, and lemon juice.
4. Process the mixture until it is completely smooth and well-mixed. This may take a few minutes, depending on the power of your food processor or blender. Scrape down the sides of the bowl as needed to ensure even blending. The mixture should transform into a beautiful, speckled butter.
5. Transfer the nasturtium butter to an airtight container.
6. Refrigerate the butter for at least 30 minutes to allow the flavors to meld and the butter to firm up slightly before using.

Expert Tips & Tricks

• Flower Power: When harvesting nasturtiums, choose blossoms that are brightly colored and free from blemishes. The more vibrant the color, the more intense the flavor. Pick them early in the morning, after the dew has dried, for the best taste.
• Herbaceous additions: While the recipe calls for just nasturtiums, feel free to experiment with other herbs. A small handful of finely chopped chives, parsley, or tarragon can add another layer of complexity.
• Garlic boost: For a more savory butter, add 1-2 cloves of minced garlic to the mixture before blending. This creates a fantastic compound butter for seafood or grilled vegetables.
• Salt Smartly: I prefer using unsalted butter in this recipe to control the salt level. You can add a pinch of sea salt to the mixture, to your preference.
• Lemon Zest: If you want to amplify the lemon flavor, try adding a teaspoon of lemon zest along with the juice. Be sure to use organic lemons for the best flavor and to avoid any pesticide residue.
• Color Preservation: The vibrant colors of the nasturtium petals may fade over time. Store the butter in an airtight container in the refrigerator to help preserve the color for as long as possible.

Serving & Storage Suggestions

Nasturtium butter is incredibly versatile. Spread it on grilled bread, melt it over steamed vegetables, or use it to finish pan-seared fish or chicken. It’s also a delightful addition to a cheese board or a picnic basket.

• Serving: For an elegant presentation, shape the butter into a log and chill it before slicing. Serve the slices on a chilled plate with crusty bread or crackers.
• Storage: Store nasturtium butter in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze the butter in small portions.
• Freezing: To freeze, wrap individual portions of butter in plastic wrap and then place them in a freezer bag. Frozen nasturtium butter will last for up to 3 months. Thaw overnight in the refrigerator before using.

FAQs (Frequently Asked Questions)

Q: Can I use dried nasturtiums for this recipe?

A: Yes, you can, but adjust the amount of salt you add to the butter accordingly. Taste the butter before refrigerating and add more salt if needed.

Q: What if my butter separates after blending?
A: This can happen if the butter gets too warm during the blending process. Place the mixture in the refrigerator for a few minutes to firm up, then try blending again.

Q: Where can I find nasturtium blossoms?
