A Food Truck and a Pear Tree

T5, E4: Vivian, her parents, and Flo pluck pears from a tree that’s been in the family for 100 years. The arrival of Vivian's cookbook sparks a well of emotions as the reality of wheeling a food truck around the country sets in. In order to get a better handle on the truck, Vivian and her crew do a practice run at the farmer's market and serve up Tom Thumb with pear relish -- a dish that pleases most but leaves a bad taste in Ms. Lillie's mouth.
