Japanese knotweed, commonly known as the "bamboo weed," is primarily recognized as a troublesome plant that gardeners struggle to eradicate. However, this unwanted guest holds a sweet secret: its stalks can be transformed into delicious desserts that will delight even the most discerning food lovers.

Japanese knotweed is widely recognized as a bothersome weed and has made it onto the list of invasive species threatening native flora. Although its cultivation is prohibited, few people know that Japanese knotweed is edible and can be used in cooking. This can serve as a method of control and source of surprisingly tasty dishes.

Japanese knotweed crumble - a surprise for the palate

Japanese knotweed crumble is a simple yet impressive dessert that will surely win your guests' hearts. It combines the tangy taste of Japanese knotweed stalks with a crunchy crumble and the sweetness of apples, creating a unique flavor composition.

Ingredients:

  • 9 oz. Japanese knotweed stalks
  • 1 tsp. sugar or other sweetener
  • 1 tbsp honey
  • 2 oz. rolled oats
  • 1 tbsp coconut
  • 2 apples
  • 0.5 oz. clarified butter
  • Optional: 0.5 oz. Sugar-free peanut butter

Preparation:

                              
  1. Thoroughly wash the Japanese knotweed stalks and remove the leaves. Peel the skin and cut into small pieces.
  2. Wash the apples, peel them, and remove the seed cores. Cut them into pieces similar in size to the Japanese knotweed stalks.
  3. In an ovenproof dish, layer the Japanese knotweed and apples. Drizzle with half the honey.
  4. In a small bowl, mix the rolled oats, coconut, peanut butter (if using), remaining honey, clarified butter, and sugar. Mix thoroughly to form a crumble.
  5. Sprinkle the Japanese knotweed and apples evenly with the crumble.
  6. Bake in an oven preheated to approximately 300°F with a grill or convection function (or approximately 340°F without additional functions) for about 20-25 minutes until the crumble turns golden brown.
  7. Serve warm with a scoop of vanilla ice cream, whipped cream, or chocolate sauce.
