Several shop owners encourage people to make their own creations rather than just choose a specialty classic sundae. Erin Cusack, visiting from Boston and stopping for ice cream at Shady Glen, 840 Middle Turnpike, in Manchester, in Manchester, has her own concoction: "My favorite ice cream is cookie dough. Then no whipped cream, but replaced with marshmallow syrup. And no hot fudge but replaced with strawberry topping. It actually blends well." Information: 860-649-4245.
