Soursop — Cups to Grams

Soursop Weights by Preparation

Soursop flesh measurement changes significantly based on how it is prepared. The whole fruit is dramatically lower in usable yield than most tropical fruits — expect to buy 3x the weight in whole soursop as you need in usable pulp.

The Soursop Fruit: Identification and Selection

Soursop (Annona muricata) is a large tropical fruit native to the Caribbean and Central America, now cultivated across tropical regions including Southeast Asia, West Africa, and Brazil. The fruit is distinctly oval to heart-shaped, covered with soft curved spines, and ranges from 1 to 4 kg at harvest. The skin is thin, dark green when unripe, and transitions to a yellowish-green when fully ripe.

Selecting ripe soursop: the fruit should yield gently to pressure (like a ripe avocado), without soft spots or significant skin discoloration. The spines will feel slightly pliable rather than rigid. Ripe soursop has a faint sweet aroma at the stem end. Underripe soursop is chalky and tannic — it will ripen at room temperature in 3–5 days once purchased. Overripe soursop has fermented-sweet flavors and very soft, nearly liquid flesh — still usable for drinks and ice cream.

The white flesh is divided into many segments, each typically containing one large black seed (approximately 1–2g each) surrounded by fibrous membrane. Removing seeds requires patience — the flesh is pulled apart by hand rather than cut, and each seed must be located individually. Wearing gloves is advisable if you are processing large quantities, as soursop juice can stain surfaces.

Culinary Applications: Smoothies, Ice Cream, and Drinks

Soursop's natural acidity (pH 3.8–4.0) and intensely fragrant pulp make it ideal for cold preparations where its delicate aromatics are not lost to heat. It is rarely cooked at high temperatures.

Soursop smoothie (1 serving): 1 cup (245g) seeded soursop puree + 1/2 cup (120ml) coconut milk + 1 cup ice + 1 tablespoon honey (optional — ripe soursop is very sweet on its own, approximately 13–15g sugar per 100g). Blend 45 seconds. This produces approximately 450ml finished smoothie. Nutritional: approximately 180 calories, 3g fiber, significant vitamin C (20–25mg per serving).

Soursop agua fresca (4 servings): 2 cups (490g) seeded puree + 4 cups cold water + 3 tablespoons sugar + 2 tablespoons lime juice. Blend smooth, strain through fine mesh sieve, serve over ice. The straining removes fibrous pulp for a cleaner drink.

Classic soursop ice cream (4 servings): 490g (2 cups) seeded puree + 240ml (1 cup) full-fat coconut milk + 200g sweetened condensed milk + 1 tbsp lime juice + pinch salt. No-churn: freeze 6 hours with one stir at 3 hours. Ice cream maker: churn 20–25 minutes at approximately 1°C.

Nutritional Profile

Per 100g soursop flesh: approximately 66 calories, 1g protein, 0.3g fat, 16.8g carbohydrate (13g sugar, 3.3g fiber), 20mg vitamin C (22% DV), 278mg potassium (8% DV), 0.6mg iron (3% DV). Soursop is notably high in vitamin C relative to its calorie content and provides a meaningful contribution to daily potassium intake. The fiber content (3.3g/100g) is higher than many tropical fruits.

Soursop seeds and leaves are NOT edible — they contain annonacin and related acetogenins, compounds that are neurotoxic in large quantities. The edible flesh and juice contain very low levels of these compounds that are considered safe in normal dietary quantities. Do not blend soursop seeds into smoothies. The seeds are easily visible (large, black, 1–2cm long) and straightforward to remove.
