A teaspoon of soursop leaf powder disappears into a smoothie. You don't taste it directly, what you get is a soft, slightly grassy depth underneath the main flavours. It works particularly well with tropical fruits, banana, citrus, and creamy bases like coconut milk or yoghurt.
Five recipes that actually work in a UK kitchen. Each makes one large glass or two small ones.
Soursop is also called graviola, guanabana, guyabano, and Annona muricata, same plant, milled fine. If you're new to the powder, see our guide to using soursop leaf powder first.
The basics
Half a teaspoon to one teaspoon of soursop leaf powder per smoothie. More than that doesn't make the smoothie taste more interesting; it just makes it grassier.
Add the powder to the liquid first, blend briefly to disperse it, then add the rest. That stops it clumping. Alternatively, stir it into a tablespoon of hot water in the cup before blending, that fully dissolves it.
1. Tropical Caribbean
The classic. Bright, fruity, easy.
- 1 ripe banana
- 200ml coconut water
- 100g fresh or frozen pineapple chunks
- 1 teaspoon soursop leaf powder
- Juice of half a lime
- A handful of ice
Blend until smooth. The lime keeps it from getting too sweet; the pineapple carries the soursop flavour.
2. West African breakfast
Heartier, good for cold mornings.
- 1 ripe banana
- 200ml oat milk
- 1 tablespoon peanut butter (smooth or crunchy)
- 1 teaspoon honey or maple syrup
- 1 teaspoon soursop leaf powder
- A pinch of cinnamon
- A handful of ice
Blend. The peanut butter and oat milk give it body; the soursop sits underneath as a soft herbal note.
3. Green soursop
Lighter, fresher, slightly savoury edge.
- 1 green apple, cored and chopped
- A handful of fresh spinach (about 30g)
- 1/4 cucumber
- A thumb-sized piece of fresh ginger, peeled
- 200ml coconut water or filtered water
- Half a teaspoon soursop leaf powder
- Juice of half a lemon
Blend until smooth. Strain through a sieve if you want it juice-like. The ginger and lemon do the heavy lifting; the soursop adds depth.
4. Berry blend
Pink, creamy, easy.
- 150g frozen mixed berries (raspberry, strawberry, blackberry)
- 100g plain yoghurt (Greek or coconut yoghurt both work)
- 100ml milk of choice (oat, almond, dairy)
- 1 teaspoon honey or maple syrup
- Half a teaspoon soursop leaf powder
Blend. Frozen berries give it thickness without needing ice. The yoghurt softens the tartness.
5. Iced summer cooler
Lighter than a smoothie, more like a slushie. Good for hot afternoons.
- 250ml coconut water
- Juice of one lime
- 6 to 8 fresh mint leaves
- 1 teaspoon soursop leaf powder
- 1 teaspoon honey (optional)
- A generous handful of ice (about 200g)
Blend until the ice breaks down into a slushie texture. Serve immediately in a tall glass.
Tips for the best blend
Frozen fruit beats ice for texture. Ice waters the smoothie down. Frozen bananas, berries, or mango give you thickness without dilution. Keep a stash of peeled, frozen banana chunks in the freezer for smoothies.
Match the soursop to a strong base. Soursop powder is gentle. Pair it with bold flavours, pineapple, ginger, lime, peanut butter, berries. It gets lost behind anything too mild on its own.
Don't sweeten until you've tasted. Most of these recipes are sweet enough from the fruit. Add honey at the end if you actually need it.
Drink fresh. Smoothies don't keep well. Anything with the powder in it should be drunk within a few hours; it'll separate if it sits in the fridge.

Frequently asked questions
Can I use whole soursop leaves in a smoothie?
Not really. Whole leaves are for brewing as tea. The powder is what's designed to be stirred or blended straight in.
How much powder per smoothie?
Half a teaspoon to one teaspoon. More than that and the flavour gets grassier, not better.
Can I substitute fresh soursop fruit for the powder?
Yes, where in season. Use about 100g of fresh soursop flesh (seeds removed) in place of the powder. The flavour profile is quite different, fruit is creamy and tropical, powder is a herbal undernote, so the recipes will taste different but still work. See our fresh soursop fruit page for availability.
Will the powder turn the smoothie green?
It tints the colour slightly. A green smoothie gets a little greener. A pink berry smoothie picks up a faint green undertone but is still pink. Most blends mask the colour completely.
