The Montshire Museum of Science asked if I'd donate a cocktail to be auctioned off in the museum's annual fundraiser. The winner happened to be The New York Times' parenting blogger, KJ Dell'Antonia. She and the family recently went to the Caribbean, where she found a love for rum-based tropical drinks. So I made her a rum-based tropical drink named in honor of her blog, The Motherlode. The biscuits are Effie's oatcakes, KJ's favorites. I'm serving the drink at a birthday party for KJ next month.
