Mary Jo always treats herself to specialty yogurts when we are in Europe. The challenge is that she does not like fruit, well, most fruit. Some flavors she enjoys are mocha, pistachio, toasted coconut and her favorite is lemon. This recipe yields about 3 quarts of thick-rich-tangy-creamy-lemony MJ-worthy goodness. Reserve some of the plain yogurt you make as a live culture, and all you will need to make endless amounts of yogurt in the future is milk.
