Oh dear. This is a bean I would LOVE to love: it grows well in my country and supposedly has so many nutrients... But...
No matter how many times I have tried, I just cannot get the beans soft enough and make the hulls come off easily... We have tried several times in my family and finally gave up - no amount of cooking makes these anything worth eating
Such a shame, as this is an old heirloom vegetable grown in Finland for centuries (just as it is grown all over Europe).. The stomach upset just isn't worth it.
So I gladly accept defeat in this and happily eat imported beans - kidney beans, chick peas, large white ones... delicious and easily digested!
