Sour Patch Kids (also known as Carambar Very Bad Kids in France, and previously known as Maynards Sour Patch Kids in Canada and the UK) are a brand of soft gummy candy with a coating of invert sugar and sour sugar (a combination of citric acid, tartaric acid, and sugar).[1] The tartaric and citric acids provide the candy with a sharp burst of tartness, while the inverted sugar gives the soft gummy its sweet flavor.[2] Sour Patch Kids Extreme, which contains malic acid in addition to the tartaric and citric acids, is considered the sourest variation in the Sour Patch line of candies.[2] The slogans "Sour Then Sweet" and "Sour. Sweet. Gone." refer to the candy's sour-to-sweet taste.[3]
