WELLFLEET — One summer day in 1932 Esther Wiles set out eight jars of homemade wild beach plum jelly at the roadside vegetable stand in front of her farm on Briar Lane. They sold like the proverbial hotcakes, and soon her husband, Leroy, built a new stand for his wife’s ever-growing assortment of jams and jellies. Today Terri Sayre, whose husband, Tim, is Esther Wiles’s grandson, carries on the family business, churning out some 40 varieties of homemade jams, jellies, pickles, and chutneys at BriarLane Jams & Jellies on Route 6. Their daughters, Amber and Ashley Grainger, are already making plans to be BriarLane’s fourth-generation family owners.

Beach plum is still the best seller, Sayre said. The fruit grows wild in the dunes on the Outer Cape, and Sayre buys from several local residents. She can never get enough, and extracting the juice is very labor-intensive, she said, adding with a laugh, “Beach plums will be the death of me.’’

Other popular flavors are wild Maine blueberry, strawberry, blackberry, peach, and raspberry; cranberry is the most popular chutney. Each generation has added new flavors. Terri’s creations include apple pie jam, strawberry jam with Chambord, and jalapeno jelly. Everything is made fresh in the 8-by-10-foot kitchen attached to the stand, sending tantalizing aromas all the way to the parking area.

Winter residents of Florida, Sayre and her helpers – usually some combination of her three children, Amber, Ashley, and Dakota Grainger – spend the summer months in the 1855 family homestead 50 yards away.

Seeing customers return year after year is especially rewarding, said Tim Sayre. “It’s nice when everyone appreciates what you make.’’
