The recipe is terrible! There is an error in quantity of flour required for bechamel - the recipe indicates about 10 times more flour than needed. Actually the ingredients listing indicates a correct amount, but when you use step-by-step cooking instructions (you get redirected to another site for that) the quantity is totally wrong. I had some doubts from the beginning, but I trusted the recipe and understood that it was wrong midway of cooking. I've checked other proper recipes for bechamel and partially managed to correct the bad sauce. Anyway, the dish was almost ruined. It looks like whoever placed this recipe here just used a combination of different recipes, one of which implied that pasta is done by the cook (not a ready-made cannelloni from a shop), hence this huge amount of flour. Apparently the "author" never cooked per the recipe offered. It's a pity that recipes are not checked for consistency.
