Guanabana juice (also called soursop juice) is one of the simplest tropical drinks to make at home. You need ripe guanabana pulp, water or milk, sweetener, and a blender. The whole process takes about 10 minutes once your fruit is prepped.
Choosing and Prepping the Fruit
A ripe guanabana gives slightly when you press it, similar to a ripe avocado. The skin turns from dark green to a slightly yellowish green, and you may notice small dark spots. If your fruit is still firm, leave it on the counter for two to three days until it softens.
Cut the fruit in half and scoop out the white, creamy flesh with a spoon. As you go, pull out and discard every black seed. This step matters: the seeds contain a compound called annonacin that can harm the nervous system with repeated exposure, so none should end up in your blender. Some people find it easiest to drop the pulp into a bowl of water and separate the seeds with their fingers. You should end up with roughly one to two cups of clean pulp from a medium-sized fruit.
The Basic Water-Based Recipe
The classic ratio is simple: fill a one-quart (four-cup) measuring container with your guanabana pulp, then top it off with cold water to reach the one-quart line. This gives you a drink that’s creamy enough to taste rich but thin enough to pour easily. For a thicker, more concentrated juice, use less water. For something lighter and more refreshing, add an extra cup.
Blend the pulp and water on high for about 30 seconds until smooth. Taste it before adding sweetener, because ripe guanabana is naturally sweet. If you want more sweetness, stir in sugar, honey, or condensed milk one tablespoon at a time. A squeeze of lime juice brightens the flavor and balances the fruit’s natural creaminess. Strain the juice through a fine mesh sieve if you prefer a smooth texture, pressing the pulp with a spoon to extract all the liquid. Many people skip straining and enjoy the thicker, pulpier version.
The Creamy Milk-Based Version
Across Latin America and the Caribbean, guanabana juice made with milk is just as popular as the water version. Replace the water with whole milk, coconut milk, or evaporated milk for a drink that tastes like a tropical milkshake. Condensed milk works as both your liquid and sweetener in one. Use the same ratio: about one cup of pulp to three cups of milk, adjusting thickness to your preference. Blend with ice for an even thicker, smoothie-like consistency.
A pinch of vanilla extract, a dash of cinnamon, or a small piece of fresh ginger are all common additions that pair well with the fruit’s tangy, custard-like flavor.
Using Frozen Pulp
If you can’t find fresh guanabana, frozen pulp packets are widely available at Latin American grocery stores and online. They work just as well for juice. Thaw the packet in the refrigerator or run it under warm water, then blend exactly as you would with fresh pulp. Frozen pulp is already seeded and cleaned, which saves the most time-consuming step of the process.
Nutrition in a Glass
One cup of guanabana pulp (about 225 grams) provides 148 calories, 46 mg of vitamin C, and 626 mg of potassium, which is more potassium than a medium banana. It also delivers over 7 grams of fiber per cup, roughly a quarter of the daily recommended intake. Most of the carbohydrates (about 38 grams per cup) come from natural sugars, so keep that in mind if you’re adding extra sweetener on top.
For healthy people, one cup of pulp or juice per day is a reasonable serving. Eating several cups daily or taking concentrated soursop supplements over long periods may pose neurological risks due to the annonacin naturally present in the fruit. Occasional, moderate consumption is the straightforward approach.
Storing Your Juice
Fresh guanabana juice tastes best the day you make it, but it holds up in the refrigerator for two to three days in a sealed container. You’ll notice the flavor and sweetness gradually fade after about four days. Give it a good stir or shake before drinking, since the pulp naturally separates and settles to the bottom.
For longer storage, freezing is your best option. Pour the juice or leftover pulp into ice cube trays, freezer bags, or small containers. Frozen at around minus 20°C (standard home freezer temperature), it stays stable for several months with minimal change in quality. When you’re ready for a glass, thaw what you need in the fridge overnight and blend briefly to restore the smooth texture.
