Understanding Freeze-Dried Natto
Traditional natto is a Japanese delicacy of fermented soybeans known for its distinct, pungent aroma and slimy, sticky texture. While fresh natto is highly nutritious, its texture can be challenging for some. Freeze-dried natto, on the other hand, is made by dehydrating the fermented soybeans, which preserves the nutritional benefits—including probiotics and vitamin K2—while changing the texture and significantly mellowing the flavor. The result is a crunchy, shelf-stable product that can be used in a variety of culinary applications.
How to Prepare Freeze-Dried Natto
Your preparation method depends entirely on your desired texture. For a chewy, rehydrated texture similar to traditional natto, you will need to add water. For a crispy, crunchy element, no preparation is needed. Many products come in whole bean, crushed ('hikiwari'), or powdered forms, offering different culinary possibilities.
Rehydrating for a Traditional Experience
If you prefer the classic natto texture without the pungent smell, rehydration is the way to go. This process is straightforward and yields a soft, flavorful bean.
- Measure: For two people, start with approximately 20g of freeze-dried natto.
- Soak: Lay the beans flat in a small, shallow dish. Add about 2.5 tablespoons of water over the beans.
- Wait: Allow the beans to rehydrate for 3 to 4 hours. The beans will swell and soften.
- Mix: Before serving, mix the rehydrated beans well. You can then add seasonings like soy sauce and mustard to taste.
Enjoying Freeze-Dried Natto as a Snack
For those who prefer a no-fuss, crunchy snack, freeze-dried natto can be eaten directly from the bag. It has a nutty, savory taste similar to roasted beans and is an excellent replacement for less healthy, processed snacks.
Creative Recipes for Freeze-Dried Natto
Beyond simply eating it from the package, freeze-dried natto can elevate many dishes. Its mild, nutty flavor and crunch make it a surprisingly versatile ingredient.
- Topping for Rice and Salads: Sprinkle whole or crushed freeze-dried natto over steamed rice, salads, or grain bowls for added protein and crunch.
- Mix-in for Soups: Stir the beans into miso soup or other hot soups just before serving to add texture and flavor without them becoming overly soft.
- Pasta and Fried Rice: Mix crushed or powdered natto into fried rice or pasta dishes during the final cooking stage to add a nutty flavor.
- Omelets and Scrambled Eggs: Fold the freeze-dried beans into omelets or scrambled eggs for a textural surprise and an extra nutritional boost.
- Yogurt and Cereal: For a unique twist, try sprinkling plain or sweetened freeze-dried natto over yogurt, cereal, or granola.
