Walnut Banana Muffin

11 Mar, 2020

I use to make this a lot when we just started eating paleo and this muffin was very popular with my son’s team-mates when they went to karate competitions and would spend the whole day in a sporthall. It supplied them with energy and of course it’s yummy.

My mom has a huge walnut tree in her backyard and every year I get a huge bag of the best quality cleaned shelled walnuts. You can appreciate my excitement if you’ve ever had to clean your own walnuts for a recipe. You need to open them slowly if you want to keep the walnut intact. You will need nice whole walnuts if you want to decorate a cake, salad or serve it with cheese. For this recipe it’s less important because the walnuts need to be finely ground for the muffin.

Walnuts have several health benefits. They are rich in antioxidants which can help fight oxidative damage in your body. Walnuts are higher in omega-3 fat than any other nuts, which may help reduce heart disease risk and it is important in the development and function of the central nervous system too. Good fats (polyunsaturated fats), support good brain function and brain health. Walnuts also contain iron, selenium, calcium, zinc, Vitamin E and some B vitamins. It fits into any style of eating because of their low carbohydrate value.

Walnuts are best stored below 25°C and low humidity. Temperatures above 30°C and 70% humidity can lead to rapid spoilage and above 75% humidity a dangerous fungus develops. The ideal temperature for longest storage is between -3°C and 0°C and low humidity.

(I use 12-cup muffin pan. Check Tips and Tricks how you can make cupcake liners from baking paper!)
