For a sweet and tropical twist, try a bagel with guava paste in Cuba. Guava paste, also known as 'guayaba,' is a popular fruit preserve made from guava fruit. It has a sweet and slightly tangy flavor that pairs perfectly with the plain bagel. Simply spread a generous amount of guava paste on a toasted bagel for a delicious and unique treat. The combination of the soft bagel and the sweet guava paste is a match made in heaven. It's a must-try for anyone with a sweet tooth.
