To store, wrap the leaves in a damp paper towel and place them in a plastic bag in the refrigerator for 3 to 5 days. This method helps maintain freshness and reduces the risk of spoilage.
Taste and Texture Characteristics
Tatsoi, known for its distinctive taste and texture, is enjoyed both in its mature and unripe forms. The young leaves are tender and bear a flavor that can enrich a variety of dishes.
Flavor Profile
Tatsoi's flavor is mild yet distinctive, with a slight peppery taste that is less pronounced than arugula. Unripe tatsoi tends to have a more subtle taste, which can be described as a blend of earthy and sweet notes with a hint of bitterness. This bitterness is typically milder than that of mature leaves, making it suitable for raw consumption. The plant is sometimes referred to as spoon mustard, which suggests its gentle mustard-like qualities without overpowering the palate.

One can sauté it with a bit of garlic and sesame oil before adding it to the main dish, or directly add it to miso soup for an Asian-inspired comfort food.
Stir-Fry Tatsoi:
Heat a drizzle of sesame oil over medium heat.
Add minced garlic, sauté until fragrant.
Stir in tatsoi leaves, cook until just wilted.
Season with soy sauce or fish sauce for an extra umami kick.
The key to maintaining tatsoi’s vibrant color and texture in stir-fries is to cook it quickly, for no more than a few minutes, which makes it a perfect last-minute addition to any stir-fried dish.
Selecting and Purchasing Tips
When visiting the grocery store for tatsoi, a leafy green vegetable, shoppers should pay attention to the freshness and storage potential of the greens they intend to purchase.
Choosing Fresh Tatsoi
Shoppers should look for tatsoi greens with vibrant green leaves, which indicate freshness. The leaves should be crisp, without any signs of wilting or yellowing. If the stems are also present, they should be firm and not slimy. Avoid tatsoi with leaves that have brown spots or seem overly wet, as this could suggest decay.
Storage and Shelf Life
After purchase, tatsoi should be stored properly to maintain its freshness. It is recommended to place tatsoi in a plastic bag with air circulation and store it in the refrigerator's crisper drawer. Proper storage will typically allow the tatsoi to remain fresh for up to a week. Checking the greens regularly and removing any that start to spoil will help extend the shelf life of the remaining leaves.
