Cook the half and half over medium-low heat with the peppercorns until hot to the touch. Put about 2/3 of the crumbled cheese into a mixing bowl, and pour the hot half and half through a strainer over the cheese, add the sugar and lemon juice and whisk until all the chunks are dissolved. Chill overnight, or at least four hours. Before spinning in your machine, mix in the reserved chunks of bleu cheese. Spin according to manufacturers instructions, and then serve it to your friends but don't tell them what flavor it is.
