I need to give you two warnings about the following information.
I don't know about longevity and safety issues of do-it-yourself (DIY), made-at-home recipes of anything involving dried milk products. So, if you decide to make a batch of home-made, "Poor Man's" "Plumpy'nut", I would not keep the finished product outside of a refrigerator. I also don't know how long it will last inside the refrigerator but to be on the safe side, I would treat it like leftovers (three (3) days) if you have added dried milk to it.
If you end up in the hospital with some type of food poisoning because you did not heed the warnings given, you accept full responsibility for your own actions. I also cannot control the cleanliness or lack of same with your mixing utensils, etc.
The other warning I would like to give you is this, this is a very powerful concoction and if you eat a lot of it, you might have to butter your hips to get your quickly-widening ass through your front door. This stuff is a very powerful emergency ration. It's not something that you sit around and eat while watching television.
"Plumpy'nut" was developed by a French Pediatrician as a food for use in famine-stricken countries.
While I don't have the formula for actual "Plumpy'nut", I can tell you what I have tried at home. It is tasty and it's no wonder it turns around severely malnourished children on death's door in a matter of a couple or a few weeks.
This is the incredibly simple recipe:
1. Dried (Powdered) Milk
2. Peanut Butter
That's it! Isn't it great? Purchase some Dried Milk, Peanut Butter and some Honey and whip up a small batch in your kitchen and try it out. You can mix it just about any way you want to, it's very versatile. Start out with a cup of dried (powdered) milk and a cup of Peanut Butter and about a quarter cup of Honey. Add more Honey as required. Just start mixing it up until it is mixed well and you should have a very, very thick goop and, VOILA! You have Poor Man's "Plumpy'nut"!
You can also use Nutella, Ovaltine or Nestle's Milo added to the ingredients or in just about any combination that your taste buds find appealing.
All of these ingredients with the exception of the powdered milk don't have to be refrigerated. These are all basically dry goods that you can use and then put back in the pantry, right? Honey, Peanut Butter, Ovaltine, Milo and Nutella don't have to be refrigerated once opened.
I'm also not a chemist or some type of food safety specialist so I don't know the long-term ramifications of combining these foodstuffs together and leaving them together for long periods of time.
I do know that if used carefully, this is a very valuable list of ingredients to have in your pantry in case of emergency. It could save your life. In the future I want to run some experiments with a Rival or Tilia Brand Food (Bag) Sealing appliance and see how everything turns out. I'd also like to contact powdered milk manufacturers and find out about the safety of that material once the foil envelope is opened and the product is added to these other ingredients and re-sealed in another air-tight bag.
My entry on Honey from over a year ago is a must-read for survival food information as well.
