Cuban Preserves: Jams, Jellies, and Tropical Fruits in Syrup

In Cuba, preserving fruit isn’t just a cooking technique — it’s an art passed down through generations, born from tropical abundance and the need to save the harvest. From the cascos de guayaba en almíbar (guava shells in syrup) that accompany cream cheese on every Cuban table, to the artisanal jams of mango and orange, Cuban preserves are a gastronomic treasure that transcends borders.

The Tradition of Preserving in Cuba

The island’s tropical climate produces fruit year-round. Before modern refrigeration, Cuban families developed preservation techniques that are now culinary heritage. The most common method: cooking fruit in almíbar (sugar syrup), taking advantage of Cuba’s abundant sugar production.

Home-based dulcerías (sweet shops), especially in provinces like Camagüey, Sancti Spíritus, and Holguín, keep this tradition alive. Each family guards their recipes closely, passing them from mothers to daughters.

The Essential Cuban Preserves

Cascos de Guayaba en Almíbar (Guava Shells in Syrup)

The undisputed king of Cuban preserves. Guavas are carefully peeled, seeded, and cooked in syrup with cinnamon and a touch of lemon. The result: translucent pink shells served with cream cheese — the most iconic combination in Cuban dessert culture.

The guava (Psidium guajava) grows wild throughout Cuba and is considered the quintessential national fruit. According to CiberCuba, guava shell recipes vary by region, from sweeter versions in the west to spicier ones in the east.

Guava Marmalade and Paste

The leftover pulp from making shells becomes marmalade, and cooking it longer produces the famous guava paste — a dense, dark, intensely sweet block cut into slices. In Miami and throughout the diaspora, guava paste is the star ingredient of Cuban pastelitos.

Dulce de Fruta Bomba (Green Papaya Preserve)

Green fruta bomba (as papaya is called in Cuba) is cut into strips or chunks and slowly cooked in syrup. The result is an amber, fibrous, fragrant sweet. In eastern provinces, it’s flavored with star anise and orange peel.

Fun fact: In Cuba, the word “papaya” has a different colloquial meaning, so the fruit is called “fruta bomba” (bomb fruit) instead.

Sweetened Shredded Coconut

Shredded coconut cooked with brown sugar produces a dense, caramelized sweet sold on the streets wrapped in banana leaves. In Baracoa, Cuba’s coconut capital, this preserve reaches its highest expression. Learn more about Cuban caramelized coconut treats.

Mango Jam

Ripe mangoes (Mangifera indica), abundant from May through August, transform into thick, aromatic jams. The biscochuelo and manga varieties are preferred for their natural sweetness. Cuba has over 40 mango varieties, as detailed in our guide to Cuban tropical fruits.

Sour Orange Jelly

Naranja agria (Citrus aurantium), essential in Cuban cooking as the base for mojo criollo, also transforms into a transparent, aromatic jelly with a perfect sweet-tart balance.

The Traditional Process

The Cuban preservation method follows steps that have changed little over centuries:

1. Selection: Ripe but firm fruits (for syrup) or very ripe (for jams)
2. Preparation: Peeling, seeding, and cutting according to the fruit
3. Syrup: Classic 2:1 ratio (sugar:water), cooked to thread stage
4. Cooking: Fruit is submerged in hot syrup and simmered slowly
5. Aromatics: Cinnamon sticks, cloves, vanilla, or citrus peel
6. Canning: In sterilized glass jars, vacuum-sealed
