It’s often used to gently steam vegetables, dumplings, meats, tofu, and even complete meals — all while preserving their natural flavor and nutrients. Learn how steaming supports gut health.

How to Use a Seiro at Home
You don’t need a professional setup to start steaming with a seiro — just a few basic tools and the right technique.
What You’ll Need
1 or more seiro trays
A pot or wok slightly smaller than the steamer
Parchment paper or cabbage leaves (optional, to prevent sticking)
Lid (wooden lid or cloth-covered bowl)
Step-by-Step
Fill your pot with about 2 inches of water and bring it to a boil.
Line the bottom of your seiro with parchment or greens to prevent sticking.
Place food inside, leaving space between pieces for steam to circulate.
Stack trays (if using multiple), then cover with the lid.
Set the seiro on top of your pot and adjust heat to medium-high.
Steam for the desired time (usually 5–15 minutes, depending on the ingredient).
Serve hot and enjoy immediately.
Easy Steaming Tips
Cut evenly: Slice vegetables or proteins into similar sizes for even cooking.
Don’t overcrowd: Steam needs space to circulate.
Flavor from below: Add kombu, herbs, or spices to the steaming water for a gentle infusion.
Revive leftovers: Use your seiro to reheat rice, dumplings, or proteins without drying them out.
How to Clean and Care for a Seiro
With proper care, a seiro can last for many years.
✅ Cleaning After Use
Allow it to cool completely before cleaning.
Rinse with warm water only — no soap, as it can absorb odors.
Use a soft brush to remove any stuck-on food.
Stand upright or hang to dry thoroughly to prevent mold.
Never leave it soaking in water or closed while damp.
❌ What to Avoid
Dish soap, bleach, or harsh cleaners
Dishwasher use
Prolonged exposure to direct sunlight or high humidity when storing
Final Thoughts
Steaming with a seiro isn’t just about cooking — it’s about slowing down, embracing tradition, and letting food speak for itself. The gentle steam preserves flavor, nutrients, and texture, while the aroma of bamboo or cypress adds a subtle elegance to each dish. Whether you’re preparing a simple plate of seasonal vegetables or a multi-layered feast, the seiro transforms everyday meals into a mindful and nourishing experience.
