Storage, Ripening & Handling
Mango skin, compost, cook, or bin it?
The internet says mango skin is a superfood. The honest answer is: it's bitter, mildly irritating, and usually best composted.

Why most skin gets binned
Pakistani mango skin is thick, bitter and contains urushiol, the same compound in poison ivy that causes contact dermatitis in a small percentage of people.
The bitterness is structural, not a cleaning problem. No washing or peeling-thin technique fixes it.
The skin-on cooking exception
Some Pakistani Sindhi recipes use unripe mango skin-on in pickles and chutneys, the bitterness balances against vinegar and chilli.
Skin-on cooking only works with unripe (green) mango. Ripe mango skin is too bitter even with strong seasoning.
Mango skin stock, yes or no?
Some chefs claim mango skin makes a fragrant stock. In practice the bitterness leaches into the liquid and overwhelms anything you'd want to use the stock for.
If you want mango flavour in a stock, use trimmings of flesh, not skin.
Composting
Mango skin composts well in a home compost bin, 6-8 weeks in summer, longer in winter.
It also works in a wormery, though red wigglers process it slowly. Cut into 2-3cm pieces to speed things up.
The contact dermatitis warning
If you've ever reacted to poison ivy, oak or sumac, you may react to mango skin. The urushiol concentration is much lower but the cross-reactivity is real.
Wear gloves when peeling if you've had any history of urushiol reactions.
Frequently asked
- Is mango skin edible?
- Technically yes, but it's bitter and a small percentage of people get a contact rash from it. Most people should peel.
- Can I use mango skin in stock?
- Not recommended, the bitterness overwhelms the broth. Use flesh trimmings instead.
- Why does mango skin irritate my mouth?
- Urushiol, the same compound found in poison ivy. Cross-reactivity is common in people who react to urushiol elsewhere.
