The most abundant food on the island was fruit. There were
groves of fruit trees, and the littluns spent most of their days eating more or less
non-stop. The fruits aren't named, but tropical fruits like star fruits, genip, sea
grapes, bananas, and chellomello would be representative of the types of fruit on such
an island. If you are trying to simulate these fruits, you could use grapes, cherries,
and kiwi; you can find star fruit in most supermarkets. You can also find unusual
varieties of bananas (or plantains), so that could be a fun thing to
try.
Palm trees are mentioned often in the book. Different
varieties of palms grow different varieties of fruits. We think of coconuts, but many
softer fruits grow on palm trees (see the link below). Dates are from palms. We thinki
of them as dried fruits; however, the boys were not drying their fruits, but simply
eating them right from the tree, sometimes before they were even ripe. Some palm fruits
you may be able to find at a grocery store (depending on where you live) are acai
berries, jubaea, butia, and peach palm fruit.
You have
mentioned pig, so having some pulled pork would be a way to represent that part of the
menu.
In chapter 4, the diet is described as "fruit and
nuts, with an odd crab or fish." So you could add crab meat and a smaller fish like
orange roughy. For nuts, almonds would be a good
choice.
Chapter 9 shows Jack's feast; they ate on palm
leaves and drank from coconut shells. It is easy to find coconut water in supermarkets
now, or you can get actual coconuts.
Have fun with your
meal!
