I've always been a fan of the salty/sweet combo (Kettle Corn, popcorn with Junior Mints for example). Probably the best version of salty/sweet I know are Salt Caramels from Fran's Chocolates here in Seattle. They are squares of light, soft caramel covered in dark chocolate and topped with a little sprinkle of sea salt. They cost about a $1 each, so when I buy them I squirrel them away in hopes Gavin won't find them.
The Haagen Dazs Fleur de Sel is kind of a revelation. They took super creamy caramel ice cream in mixed in mini caramel-filled chocolates. The caramel remains soft and has a slightly salty tinge to it. It is one of the most fattening ice creams I've seen (280 calories and 17 grams of fat per 1/2 cup). Ounce for ounce though, it is the most flavorful and satisfying ice creams I've ever had. Hopefully I can stop at just 1/2 a cup...per day.
