How to Make Natto: A Comprehensive Guide

Natto, a traditional Japanese delicacy, is renowned for its unique sticky texture and distinctive aroma, packed with probiotics and nutrients. Making it at home is simple with just a few key ingredients and steps.

First, gather 2 cups of whole soybeans, 1 packet of natto spores ( Bacillus subtilis ), and a natto fermenter or an insulated container. Start by soaking the soybeans in water for 12-18 hours until they double in size. Drain and rinse thoroughly. Next, cook the beans in a pressure cooker for 45 minutes (or regular pot for 6-8 hours) until soft but not mushy. Let them cool to about 40°C (104°F)—critical for activating the spores.

Mix the natto spores with 2 tablespoons of warm water (40°C), then gently combine with the cooked beans. Transfer the mixture to a clean, sterilized container, cover with a breathable lid (like parchment paper), and ferment at 40°C for 24 hours. For optimal flavor, refrigerate for an additional 24 hours to develop stickiness and umami.

To serve, stir vigorously to create the signature web-like threads, and add toppings like green onions, mustard, or soy sauce. Enjoy with rice for a nutritious breakfast or snack! Homemade natto is fresher and more flavorful than store-bought, offering a healthy boost to your diet.
