Last week the topic of the latest installment in Edible’s How-To lecture series was Dairy. Anne Saxelby of Saxelby Cheesemongers started off the evening with a discussion of affinage, or the art of maturing and aging cheeses, showing three different blocks of the same cheese at different stages courtesy Jasper Hill Farm. Fromager Tia Keenan continued with a lecture on cheese boards, using cheese from Lucy’s Whey.
