Well, as far as i know, in the US cornstarch is made from maize, 
whereas, as most folks on the list know, the word "corn" used in 
other places can refer to the local primary grain, often but not 
always wheat.

Of course maize starch is not the only (relatively) colorless 
thickener for cooking, as the recipe above shows. This wheat starch 
is what's called amidon in French, i believe.

So, where is arrowroot from originally? Was it used anywhere in "period"?
