Norwegian food lafsa

I tried to find the pic of that food in net but failed, anyway today Arild treat us with Norwegian food Lafsa. First its look likes crispy biscuit. After keep it in boiled water for 15/20 minutes covered by plastic or towel, it become soft then we eat it by butter and sugar and cinnamon (daruchini). WOW so delicious. In Bangladesh we also take rooty by covering butter and sugar. Thanks Arild .
