###Ingredients
***1 Overripe mango - with skin** get these as waste from the market, they can have dents and bruises it doesn't matter. We will dehydrate the mango until it becomes leather-like.
***Potato starch - 15 g** functions as the polymeer (makes the mango puree harder)
***White vinegar - 15 gr** vinegar is almost always added to starch-based biopolymers to change the molecular structure of the starch, making it stronger and more workable
***Potato starch - 1 tbsp (10 g)** functions as the polymeer (makes the mango puree harder)
***White vinegar - 1 tbsp (8 gr)** vinegar is almost always added to starch-based biopolymers to change the molecular structure of the starch, making it stronger and more workable
***Salt - 5 gr** as a preservative and stabilizer.
***Vegetable oil - 1 tbsp** as a release agent for the mould.

- Pour the paste onto the surface or mould and spread it out evenly, knock it on a hard surface gently to even it out more.
- Heat the oven to 50 degrees Celcius on the fan setting and put the paste into the oven for at least 16 hours (you can spread it out over a few days with airdrying in between). If your oven allows it without turning itself off: keep the door slightly open with a cloth to let the moisture escape).
- Carefully peel thea leather off the tray, flip it, and check if the bottom has fully dried. If not, put back in the oven with the moist side up for another few hours.
- Optional: you can airdry the leather as well, but there is some more risk of molding. Don't dry it in direct sunlight.

###Variations
- Add a **natural colorant** such as a vegetable dye or water-based ink (e.g. hibiscus, beetroot, madder). The puree is acidic (PH6-7), consider this in your choice of colorant. Dissipate some more water or to compensate for the added liquid. Adding spices may also work to create color (and smell variations).
- Add 1-2 tablespoons of **melted bees wax** for a more rigid, more water proof mango leather.
- Add 1 tablespoon of **melted bees wax** for a more rigid, more water proof mango leather.
-**Stiffeners** such as fibres, yarn or natural debris may be added for more structure and reinforcement.
-**Other starches** will work, pick whatever is (organically) produced locally.
- For recipe made of local produce, rather than local waste, try other **fibrous fruit waste** like, apples, peaches, plums or even rhubarb.
