Chinkapin, Castanea pumila
This shrub grows to about 3.5m.
The seed can be eaten raw or cooked. Sweet with a nice nutty flavour, it is very acceptable raw and has a superior flavour to sweet chestnuts (C. sativa).
When baked it becomes even sweeter and develops a floury texture, it makes an excellent potato or cereal substitute.
The seed is quite small, about 2cm. It is sold in local markets in America.
The seed husks only contain one (rarely two) seed.
The seed contains 45% starch and 2.5% protein.
The bark, leaves, wood and seed husks all contain tannin.
Wood - coarse-grained, hard, strong, light, durable, easy to split. It weighs 37lb per cubic foot.
Too small for commercial use, but it is occasionally used for fence posts, fuel etc.
