Plukentia is very easy to grow and can flower within 6 months. The problem is processing the harvested fruits. We have been growing sacha inchi for years and selling the nuts off and on at our farmers' market. The cleaning of the nuts is a tedious chore.

This is very useful commentary. I have a theory that food items that are difficult to process by hands in quantity are likely ones we don't need to eat much of or else, can be problematic if eaten in excess. Anyone who has attempted to extract a single almond from a fruit will know how much a bag of almonds is really worth.
In many cultures that do not have mechanization, a few nuts - like 3 - would be added to an entire recipe. Cashews also fit the bill. From these comments I would put sacha Inchi int he same category. The good news is, health benefits are likely to come from just a few of these in the diet.
Changing the subject, who is game to trade for some seeds?
