Sweethearts (also known as conversation hearts) are small heart-shaped sugar candies sold around Valentine's Day.
Each heart is printed with a message such as "Be Mine", "Kiss Me", "Call Me", "Let's Get Busy", "Miss You", or "I'm Yours".
[4] Daniel Chase, Oliver's brother, began printing sayings on the candy in 1866.
[6] Line extensions carrying the Sweethearts brand include chocolates and sugar-free hearts.
[6] Necco produced the hearts year-round, but mixing of colors and packaging were ramped up beginning in September to meet the demand for the product at Valentine's Day.
[13] Sweethearts returned in 2020 with the original flavors from before Necco's 2010 change, but due to equipment problems, the familiar sayings were largely either incomplete or missing entirely.
[14] The main ingredients are corn syrup, sugar, gelatin, and various types of food coloring.
