How To Make Mouthwatering Star Fruit Jam || Original Jam Recipe (2024)

Here at Blue Osa flavorful, fun, fruity jams are our JAM! We are so lucky to be living in a part of the world with access to so many exotic fruits. One of the most beloved fruits out here at our beachfront yoga retreat center is characterized by its unique shape.

If you don’t have access to starfruit, you can substitute pineapple.

What is Carambola? What is Star Fruit? How do you eat a Star Fruit?

The Carambola, or Star Fruit, is a plant originally hailing from Southeast Asia. Over time, through increasingly globalized trade routes, this special fruit made its way over to Central America. Since then this fruit has become a beloved addition to Costa Rican cuisine.

The Starfruit thrives out here in Costa Rica due to all of the humidity and rain we receive each year. The Carambola tree can grow up to 25 feet tall and will live for over 40 years in the wild! Just one tree has the capacity of producing up to 400 pounds of fruit a year!

While its shape is what makes this fruit so well-known, we absolutely love the tangy-sweet flavor it embodies. To eat Star Fruit is to fully embrace the flavor of summer! Get the taste of being at a jungle beach retreat with this delicious, beautiful, tropical fruit!

Starfruit is super refreshing, and you will notice its gentle tang dance across the palette from the first bite! Its flavor is super versatile, which adds to what makes it so special. We love to spread this Starfruit Jam onto fresh bread, muffins, or other pastries.

Not only do we love Star Fruit in jam, but we also make this fruit a staple in other delicious plates such as the Blue Osa Star Fruit Pie or Star Fruit Tart!

Here at Blue Osa, we are known for our delicious, fruity salad dressings that freshen up any plate of greens. The Star Fruit Salad Dressing created here in our Blue Osa kitchen is one of the most beloved salad-toppers we have created.

What are the health benefits of Starfruit?

  • Starfruit is super low in calories: 100g provides just 31 calories and packs a powerful nutritional punch.
  • It contains a dietary fiber that helps to protect the mucous membrane of the colon from exposure to toxic substances.
  • Starfruit is high in Vitamin C! Making it an awesome, natural antioxidant.
  • High in Vitamin B which aids with essential functions of the body relating to stress-management and metabolism.

Blue Osa’s Star Fruit Jam Recipe

Want to learn how to make this special fruit into a delicious, tangy jam? We recommend spreading this jam onto breads, cakes, muffins and anything of the sorts!

We are so excited to be sharing our healthy Star Fruit Jam recipe with you. If Star Fruit is not available at your local grocery store, no sweat! This delicious jam recipe can be made with our other favorite sweet & sour fruit, the Pineapple!

Star Fruit Jam Ingredients:

  • 5 cups fresh Starfruit (or substitute for Pineapple)
  • 1 ½ cup unprocessed cane sugar (if using Pineapple, go for 1 ½ cups sugar)
  • 2 tablespoons vanilla extract
  • ½ teaspoon cardamom
  • ½ teaspoon cinnamon
  • 1 tablespoon lemon zest or 1 tablespoon of grated ginger
  • 2 tablespoons lemon juice


Cut the fruit into even pieces: Thoroughly wash each fruit, cutting off the ends and carefully removing the skin. Then slice out the core and chop the fruit into even pieces

Mash the fruit and sugar: In a bowl, combine the pieces of cut up Starfruit with the sugar, mashing them together with a potato masher or a fork. Breaking down the fruit before cooking it helps to speed along the process.

Heat the mixture: At medium-high heat, stir until the fruit and sugar begin to simmer. Then add the vanilla, cardamom, and cinnamon. Mix well, then increase the heat until your mixture begins to boil. Let the mixture boil for 5-10 minutes, STIRRING CONTINUOUSLY as to not risk burning the jam. Once the jam has a glossy sheen to it, you can turn off the stove and cover the pot. Leave the mixture to cool completely overnight.

Finalizing your jam: The next day, return your jam to heat and let simmer, stirring continuously. Then add in the lemon juice and grated zest. Keep stirring for about 20 minutes until you have the texture and consistency you desire. Take off heat, and place in a jar, sealing tightly. Let cool before putting it in the refrigerator.
