📝 About This Recipe

Nimame is a soul-soothing staple of Japanese home cooking, representing the heart of the 'Washoku' philosophy. These dried soybeans are slowly rehydrated and simmered until they reach a buttery tenderness, glazed in a delicate balance of sweet sugar and savory shoyu. It is a dish that celebrates patience and simplicity, offering a nutrient-dense side that is as comforting as it is elegant.

🥗 Ingredients

The Beans

  • 200 grams Dried Soybeans (rinsed thoroughly; use high-quality non-GMO beans if possible)
  • 800 ml Water (for soaking and initial boiling)
  • 1/4 teaspoon Baking Soda (optional, helps soften the bean skins)

The Simmering Liquid

  • 2 cups Dashi Stock (kombu and katsuobushi based, or vegan kombu dashi)
  • 100 grams Granulated Sugar (adjust slightly based on preferred sweetness)
  • 2 tablespoons Japanese Soy Sauce (Shoyu) (use usukuchi/light soy sauce for a lighter color if desired)
  • 1 tablespoon Mirin (adds a beautiful glossy sheen)
  • 1/2 teaspoon Salt (to balance the sweetness)

Aromatics and Variations

  • 1 piece Dried Kombu (about 2 inches square, cut into small squares)
  • 1/2 small Carrot (cut into 1cm cubes for texture and color contrast)

👨‍🍳 Instructions

  1. 1

    Rinse the dried soybeans under cold running water to remove any dust or debris. Place them in a large bowl and cover with 800ml of water. Let them soak for at least 8 to 12 hours; the beans should double in size and lose their round shape, becoming more oval.

  2. 2

    Drain the soaking water and transfer the beans to a heavy-bottomed pot. Add fresh water until the beans are covered by at least 2 inches.

  3. 3

    Bring the pot to a boil over medium-high heat. Once boiling, you will see white foam (scum) rising to the surface. Use a fine-mesh skimmer or spoon to carefully remove this foam to ensure a clean flavor.

  4. 4

    Reduce the heat to low. Add the baking soda if using. Simmer the beans uncovered for about 40-60 minutes. Keep an eye on the water level; if the beans become exposed, add a little more hot water.

  5. 5

    Test a bean for doneness by pressing it between your thumb and pinky finger. It should be soft enough to crush easily. Once soft, drain the beans into a colander.

  6. 6

    Wipe the pot clean and return the beans to it. Add the 2 cups of dashi stock, the kombu squares, and the cubed carrots.

  7. 7

    Bring to a gentle simmer over medium-low heat. Add half of the sugar (50g) and the salt. Simmer for 10 minutes. Adding sugar in stages prevents the beans from toughening.

  8. 8

    Add the remaining sugar and the mirin. Place an 'Otoshibuta' (a dropped lid) or a piece of parchment paper directly on top of the beans to ensure they stay submerged and cook evenly.

  9. 9

    Simmer for another 15 minutes. Finally, pour in the soy sauce. Simmer for a final 10-15 minutes until the liquid has reduced by about two-thirds and looks syrupy.

  10. 10

    Turn off the heat. Let the beans cool completely in the liquid. This 'resting' phase is crucial as the beans will absorb the flavors more deeply as they cool.

  11. 11

    Transfer to a serving bowl or an airtight container. The flavor is often even better the next day!

💡 Chef's Tips

Always use fresh dried beans; old beans take significantly longer to soften and may remain grainy. Never add the soy sauce and sugar at the very beginning; the high concentration of solutes can draw moisture out of the beans and make them tough. If you don't have an Otoshibuta, a crumpled piece of parchment paper with a few holes poked in it works perfectly to circulate the heat. For a deeper flavor, you can substitute dark brown sugar or 'Kurozato' for a portion of the granulated sugar. Store leftovers in the refrigerator for up to 5 days; they also freeze remarkably well for future bento meals.

🍽️ Serving Suggestions

Serve as a side dish (kobachi) alongside grilled salted mackerel (Saba Shioyaki) and miso soup. Pack into a bento box as a protein-rich filler that tastes great at room temperature. Pair with a chilled glass of Junmai Ginjo sake to complement the sweet-savory profile. Mix a spoonful of the beans and their syrup into hot steamed white rice for a simple treat. Serve alongside pickled ginger and blanched spinach with sesame dressing for a balanced vegetarian meal.
