Sharifa (Custard Apple / Sitaphal): How to Tell It’s Ripe, Eat Safely
How to tell if a custard apple is ripe: look at the gaps between the bumpy segments. When they widen and show a creamy, pale yellow colour, and the fruit gives softly under your thumb, sharifa is ready. Buy them firm with those gaps just starting, ripen at home for 2 to 4 days, and eat within a day of softening, because sharifa goes from perfect to split and black very fast. This guide covers picking, ripening, the fridge question, eating around the seeds safely, recipes, and how much suits a diabetic.
In brief
- Ripe: segments separating, cream or yellow-green in the gaps, soft give, sweet smell
- Buy: firm, pale green, no black patches, stalk attached, gaps just starting
- Ripen: 2 to 4 days at room temperature; faster in a paper bag or rice
- Fridge: only once ripe, for 1 to 2 days. Pulp freezes well
- Seeds: never chew, crush or grind them. Spit them out whole
- Season: roughly August to November in Pakistan and India, peaking in autumn

How to tell if a custard apple is ripe (at the stall and at home)
Sharifa (sitaphal, sugar apple) is picked mature but hard, because a ripe one bruises and splits in a basket. Your aim at the stall is a fruit that’s mature enough to ripen well, not one that’s already soft.
- Look at the gaps between the bumps. On a mature fruit the lines between segments turn creamy white or pale yellow. Tight, deep-green lines mean it was picked too early and may never sweeten.
- Check the colour. Pale green to yellow-green is right. Dark green all over is immature. Big black patches mean bruising or rot.
- Press very gently. For eating tomorrow, a slight give. For later in the week, firm. Mushy or leaking fruit is too far gone.
- Smell it. A sweet, custardy smell means it’s close. A sour or fermented smell means it’s past.
- Keep the stalk on. A fruit with its stalk keeps better. A hole at the top lets in fruit flies.
- Buy only what you’ll eat in 4 or 5 days. Sharifa waits for nobody.
A fair stall signal: the seller keeps fruit in a single layer, not piled in a heap where the bottom ones get crushed. Prices drop sharply at the season’s peak, which is the best time to buy.

| Arka Sahan | A hybrid from India’s horticulture research institute in Bengaluru | Fewer seeds, sweeter, keeps a bit longer |
| Local desi sharifa | Punjab and Sindh in Pakistan; Rajasthan, Gujarat, Madhya Pradesh in India | Smaller, very sweet, more seeds |
| Ramphal / Lakshmanphal | Related Annona fruits, sold alongside | Different shapes and flavour; the same seed caution applies |
How to ripen sharifa at home
- Room temperature: spread them in one layer on a plate or tray, not touching, out of the sun. Most ripen in 2 to 4 days.
- Faster: put them in a paper bag with a ripe banana, or bury them in a tin of rice or wheat, an old trick that traps their own ripening gas. Check every day.
- Check daily. Once the segments separate and it feels soft, eat it that day or move it to the fridge.
Custard apple in fridge: yes or no?
Only once it’s ripe. An unripe sharifa put in the fridge gets chill damage: the skin turns black and the flesh stays hard and never sweetens properly. A ripe one keeps 1 to 2 days in the fridge; the skin will still darken, but the pulp stays good.
For longer, freeze the pulp. Scoop it out, remove every seed, and freeze in an airtight box; it keeps about 3 months and is perfect for shakes, rabri and kulfi.
How to eat sharifa safely around the seeds
Each segment of pulp wraps around a hard, shiny black seed; the seeds are toxic if chewed, crushed or powdered. Swallowing one whole by accident usually just passes through, but don’t make a habit of it, and never let small children eat around seeds on their own.
- Wash the fruit under running water and pat dry.
- Break it in half with your hands. A ripe one pulls apart easily.
- Pull out one segment at a time, eat the creamy pulp, and spit out the seed.
- For children or for recipes, press the pulp through a large-holed sieve or pick seeds out with a fork. One medium fruit gives roughly 100 to 150 g of pulp.
- Throw the seeds and skin away. Don’t let children play with the seeds, and keep them away from pets.
Our earlier piece on sharifa seeds and why they’re toxic explains the seed danger in more depth, including why the old habit of using crushed seeds on hair for lice is dangerous (the powder can seriously injure the eyes).
What sharifa gives you, and can diabetics eat custard apple?
About 100 g of pulp gives roughly 90 to 100 kcal, around 3 to 4 g of fibre, a good dose of vitamin C, and some vitamin B6, potassium and magnesium. It’s a filling, energy-dense fruit. That’s the honest benefit list. It won’t fix weakness, anaemia or low weight on its own, though it’s a useful food for someone who needs to eat more.
For diabetes: sharifa is one of the sweeter fruits. It isn’t banned, but portion matters. Half a medium fruit (about 60 to 75 g of pulp) as your fruit serving, eaten after a meal rather than on an empty stomach, suits many people. Don’t have it with other sweet fruit or in a sweetened shake; check your two-hour sugar the first few times. Our blood sugar chart gives the targets to check against.
In English it’s called custard apple or sugar apple, and neither is an exaggeration. It’s one of the sweetest fruits sold in desi markets.
Recipes: shake, rabri and chaat
Sitaphal shake (serves 2)
Blend 1 cup seedless pulp (from about 2 medium fruits) with 350 ml cold milk and a pinch of elaichi. It’s naturally sweet, so no sugar. Don’t over-blend: the grit near the seeds can turn it slightly bitter. Drink it fresh.
Sitaphal rabri (serves 4)
Simmer 1 litre full-cream milk, stirring, until it reduces to about 400 ml. Add 1 tbsp sugar only if needed, cool completely, then fold in 1 cup seedless pulp. Chill. Add the fruit only to cold milk, or the pulp can taste bitter and the milk may split.
Winter fruit chaat (serves 2)
Mix half a cup sharifa pulp with 1 chopped apple, half a cup of guava cubes, a squeeze of lemon and a pinch of chaat masala. The tang cuts the sweetness.
Good combo: sharifa with dahi or a few nuts, for protein to go with its sugar. Not for daily use: sitaphal ice cream and basundi, which are delicious desserts, not fruit servings.
Skin and hair: pulp yes, seeds never
A little mashed pulp with plain dahi is a mild, moisturising face pack. Mix 1 tbsp seedless pulp with 1 tsp dahi, apply to clean skin for 10 minutes, rinse with cool water, once a week. Patch test inside your elbow for 24 hours first; skip it on broken skin and stop if it itches.
Never use crushed seeds, seed oil or leaf pastes on skin, scalp or hair. Seed preparations can burn skin and damage eyes; it’s not worth the risk for lice or dandruff when safe pharmacy treatments exist.
In many homes sharifa is called a “thandi” (cold) fruit, and children with a cough or cold aren’t allowed any. That’s tradition. Only that. There’s no evidence ripe sharifa gives anyone a cold, though very chilled fruit can irritate an already sore throat, so room temperature is kinder. Elders also used the leaves and seeds for lice, wounds and more; the leaves and seeds contain compounds that are toxic, so those uses belong in the past. The pulp is a food, and a good one. For a child who’s sick and off food, a few spoons of seedless pulp is fine; a child who stops drinking, has a fever of 39 °C or above, or is getting drowsy needs a doctor.
Myths and surprising facts
Myth: sharifa and milk together are harmful
Sitaphal shake and rabri are safe combinations. If the milk is hot, the fruit can turn bitter and curdle it, which is a taste issue, not a poison.
Myth: black skin means the fruit is spoiled
A ripe sharifa’s skin darkens fast, especially after chilling. Open it. If the pulp is creamy white and smells sweet, it’s good. Brown, sour or slimy pulp goes in the bin.
Did you know? Sharifa isn’t native to South Asia. It came from tropical America and has grown here so long that many people assume it’s an ancient local fruit.
Seeds: never chew, crush, grind or use them on skin or hair. Small children: serve seedless pulp only and supervise, because the seeds are a choking and poisoning risk. Babies from 6 months can have smooth seedless pulp in small amounts, with nothing added. Diabetes: half a medium fruit as a serving after a meal, and check your readings. Kidney disease with a potassium limit: ask your kidney team how much fits. Weight goals: it’s energy-dense, so one small fruit counts as a real snack. Allergy or stomach upset after eating it means stop and, if symptoms are severe, get checked.
Sharifa questions people ask
How can you tell if a custard apple is ripe?
The segments separate, the gaps turn creamy or pale yellow, and it gives softly when pressed. It should also smell sweet.
Can we keep custard apple in fridge?
Only once it’s ripe, for 1 to 2 days. Unripe sharifa in the fridge goes black and never sweetens properly.
Can diabetic patient eat custard apple?
Yes, in a small portion. Half a medium fruit after a meal as your fruit serving suits many people; check your two-hour reading to see how you respond.
How do I ripen custard apple quickly?
Put it in a paper bag with a ripe banana, or bury it in rice or wheat. It usually ripens in 2 to 3 days. Check it daily.
What happens if you accidentally swallow a custard apple seed?
One whole seed swallowed by accident usually passes without harm, because the hard coat keeps it intact. Chewed or crushed seeds are the danger; if a child has chewed several seeds or feels unwell, get medical advice.
Why does my custard apple split and go black?
It’s overripe or was chilled before ripening; eat sharifa within a day of it softening. Split fruit with sweet-smelling pulp is still fine if eaten quickly.
Can I eat custard apple in pregnancy?
Yes, the seedless pulp is a fine food in normal portions. Keep an eye on the portion if you have gestational diabetes.
Is custard apple good for weight gain?
It’s energy-dense and filling, so it can help as part of eating more overall. Pair it with milk or nuts for protein.
Can I give custard apple to my baby?
From 6 months, a little smooth, completely seedless pulp is fine. Don’t add sugar and watch closely.
Does custard apple cause cold?
No. The idea comes from its “cold” label in tradition. Very chilled fruit can irritate a sore throat, so serve it at room temperature.
How long does custard apple pulp last in the freezer?
About 3 months in an airtight box, with all seeds removed. Use it straight from frozen in shakes or rabri.
