These addictive truffles were inspired by some served at the prestigious Magnolia Grill in Durham, North Carolina, a restaurant known nationwide for its innovative desserts. Whereas the chef there uses dry-roasted peanuts, I much prefer the large, toothsome, regular goobers I order routinely from Aunt Ruby's in Enfield, North Carolina (1-800-843-0105), and for even smoother and richer texture, I do add butter to the chocolate. If ever the affinity between bacon and peanut butter and/or chocolate were questioned, these truffles serve as undeniable proof. Stored in an airtight container, the truffles keep in the refrigerator up to about a week and are best served slightly chilled.
