I love Ymer and Ymerdrys. Unfortunately you've about as much chance of finding them in a UK supermarket as you have of trying to buy burgers that don't contain a slice of donkey. Given Thomas only manages to go to Denmark once every couple of years he came up with a cunning plan this time. He removed three tablespoons from our carton of Ymer and made his own yogurt with it. Hey presto! It worked and definitely tasted more ymery than anything you get here. Unfortunately the rye bread they sell here is full of seeds so not good as the basis for ymerdrys so we're back to the drawing board... unless I can convince our Danish family and friends to visit at monthly intervals with a case full of these two delicacies.
