How To Make Sour Cream Japanese Knotweed Cookies

Not all people are familiar with Japanese knotweed. Most people consider this a noxious and obnoxious weed. It is an invasive plant that will give you a headache if it gets out of hand. It grows so fast that it is famous for damaging building structures. It targets weak points such as cracks in masonry. It then attempts to grow through them. Despite the persistent belief that it is harmful and a nuisance weed, it has its own benefits. There are many uses of this weed that not everyone knows about. One of these is its usage in recipes.

Japanese knotweed is full of Vitamin A and Vitamin C. It also has Potassium, Fiber, and Manganese. It looks like Rhubarb and even smells like it. You can use Japanese knotweed in almost every recipe you can use Rhubarb in. The only difference is it doesn’t cook down as much as a Rhubarb. You have to dice it a little smaller. It has a more solid consistent shape.
