Retort pouches use the same technology that has been used in MREs (Meal, Ready-to-Eat) by the military for decades. As the technology has matured you now see this technology used with various items food from fish and meat to rice and beans. The process combines heat and pressure along with a special multilayer packaging to create a product that is commercially sterile and can be safely kept at room temperature for extended periods of time.
Need to eat in a hurry (because your SO busy)? All you need to do is tear the pouch open halfway at one end and place it in the microwave on high for approximately 90 seconds. Its like magic-o! I'm sorry that was probably racist. Es como magia! (thanks Google translate)
The pic looks O.K. but I suppose only the taste will really tell us how good these actually are. If you are feeling up to it - check out the Comali Foods website and taste the products for yourself and make sure to let me know how it works out. In the meantime I might stick to making them at home, where I can drink the water.
