Use a blue cheese you enjoy; the flavor profile of the cheese will come through in the ice cream. A blue d'Auvergne would be mild, slightly spicy and slightly sweet; a Gorgonzola would be bold, intense and complex. A Danish bleu would be the mildest choice; the milder cheeses will need less sugar. Adapted from a recipe at Serious Eats. http://bit.ly/fawLd8
