How do I use this starter to make natto at home?

Using the XUSHIKEJI sachets is straightforward: cook soybeans thoroughly, cool them to the recommended temperature, then mix in one 2g sachet and keep the beans in a warm, stable environment for fermentation. Maintain cleanliness and correct temperature to get consistent results.

• Use one 2g sachet per batch (sufficient for typical home portions).
• Cook soybeans until tender, then cool to about 40–45°C before inoculating.
• Keep beans in a warm place (around 40°C) for 18–24 hours for best texture.
• After fermenting, refrigerate to develop flavor and stop activity.

What can I expect in texture and flavor after fermentation?

Fermented beans develop the characteristic sticky strings and a savory, umami-forward aroma typical of natto. Texture can range from mildly sticky to very viscous depending on fermentation time and temperature control.

• 18–24 hours yields balanced stickiness and mild aroma.
• Longer fermentation intensifies scent and sliminess.
• Cooling in the fridge mellows flavor and firms texture slightly.
• Stirring before serving increases stringiness and creaminess.

What are practical tips to improve success with home fermentation?

Small technique adjustments produce more reliable outcomes: measure temperatures, keep a sterile workspace, and follow recommended bean preparation. Consistent warm conditions and single-use sachets reduce contamination risks.

• Sanitize utensils and containers to avoid unwanted microbes.
• Use a yogurt maker, oven with light on, or insulated cooler to hold steady heat.
• Follow one sachet per batch for predictable results.
• Store unused sachets sealed in a cool, dry place within 360 days.

How should I store and handle the product for best shelf life?

The product is packaged in individual bags to keep each dose fresh; store sealed sachets in a cool, dry spot away from direct sunlight. Use within the labeled 360-day shelf life and discard any sachet that shows moisture or damage.

• Keep unopened sachets in a pantry or refrigerator if your climate is warm.
• Avoid exposure to heat, humidity, or direct sunlight.
• Use each 2g bag only once to reduce contamination risk.
• If damaged or wet, do not use the sachet for fermentation.
