This sounded like it would be a delicious cheesecake with a tart palate cleansing piquancy that would allow it to be served after a summer meal of Chesapeake steamed crabs & pickled shrimp. Mmmmm, summer is here! The cook time includes 140 minutes of chilling time as well so it is really not cooking forever! Please note I will chill this overnight to let the custard firm up & better develop its flavor. From an article on vanilla by Terra Brockman in Food & Drink, a weekly guide to enjoying eating from Tribune. Terra wrote, "Blackbird restaurant pastry chef Tim Dahl likes to use organic Bourbon vanilla from Singing Dog Vanilla, an Oregon firm, for this crustless cheesecake. The marmalade makes 2 1/2 cups; refrigerate for up to a week to use on toast, pancakes or waffles."
