Fudge is a type of sugar candy that is made by mixing sugar, butter and milk, heating it to the soft-ball stage at 240 °F (115 °C), and then beating the mixture while it cools so that it acquires a smooth, creamy consistency. In texture, this crystalline candy falls in between fondant icing and hard caramels.
Fruits, nuts, chocolate, caramel, candies, sweets, and other flavors are sometimes added either inside or on top.
Fudge is often bought as a gift from a gift shop in tourist areas and attractions.
