A taste of the Hampton’s–that’s what Ina has planned for her friend Jack Pearson’s weekend guests. While they are touring the local food sites–a wonderful vineyard, farm stand and cheese spot, Ina’s whipping up a delicious Rare Roast Beef and Horseradish Sandwich, a Montauk Seafood Salad and Plum Raspberry Crumble--using only local produce.
