Is Pure Tarragon Naturally Gluten-Free?
Yes, pure tarragon (Artemisia dracunculus) is an herb and, as such, does not contain any gluten proteins. Gluten is a protein found exclusively in certain grains like wheat, barley, and rye. Since tarragon is a member of the sunflower family (Asteraceae), it is not a grain and is completely safe for a gluten-free diet in its unadulterated form. This holds true for both fresh tarragon leaves and dried, single-ingredient tarragon.
The Importance of Avoiding Cross-Contamination
While the herb itself is safe, the primary risk for celiac patients comes from cross-contamination. This can occur at several points before the tarragon reaches your kitchen:
- Processing Facilities: Many herbs and spices are processed in facilities that also handle gluten-containing products, which can lead to accidental commingling. This is especially true for pre-packaged spice blends.
- Packaging: Equipment used for packaging can transfer gluten from one product to another. Manufacturers that process both gluten-free and gluten-containing items should have strict protocols in place to prevent this, but it is not always a guarantee.
- Retail and Bulk Bins: Spices sold in bulk bins at grocery stores are a high-risk area for cross-contamination. Customers can use the same scoop for multiple products, potentially mixing gluten into otherwise safe herbs.
To be certain, always purchase tarragon that is explicitly labeled as "Certified Gluten-Free" to eliminate any risk.
How to Safely Incorporate Tarragon into a Gluten-Free Diet
For a safe culinary experience, follow these guidelines when using tarragon:
- For Dried Tarragon: Opt for brands that carry a certified gluten-free logo. These brands undergo rigorous testing to ensure their products are below the 20 parts per million (ppm) gluten threshold required for certification. Avoid generic or store-brand bulk spices that do not specify their gluten-free status.
- For Fresh Tarragon: When buying fresh tarragon, the risk is minimal. However, consider buying from a local farmers' market or reputable produce supplier. At home, wash the leaves thoroughly under running water before use. When handling, use clean utensils and cutting boards to prevent any gluten transfer from other foods in your kitchen. Wash your hands thoroughly before and after handling other ingredients.
- Growing Your Own: For the ultimate peace of mind, growing tarragon at home is the safest option. The plant is a perennial, and French tarragon, the most flavorful variety, can be grown from cuttings.
