- Most Americans & Canadians are completely unaware of the fruit. Some Brazilians are unaware of the nut. I met at least a couple Brazilians (in Sao Paulo and another region that don't have cashew trees) who've eaten the fruit but have never had cashew nuts and didn't even know about the nut!
- All this tasty fruit exists above the nut, but--as far as I can tell--no effort is make to export the fruit. It might the problem of creating a market for a new product, or maybe the fruit doesn't travel well. Cashew juice is widely available in Brazil, but I wonder if most of the fruit goes to waste?
- Cashew nuts and ironically Brazil nuts are quite pricey in Brazil (at least in Sao Paulo). My thinking is that cashews are perceived as a rich person's snack in Brazil and priced accordingly. This leads to the circular problem that ordinary Brazilians don't eat many cashew nuts because it's expensive, so the domestic market for them stays small and for the affluent.
