Rosketti or rosketi are traditional Chamorro cornstarch cookies.

The primary ingredient for rosketti is typically corn starch.

Other ingredients include flour, sugar, butter or shortening, milk or cream, eggs, baking powder, and vanilla.

The taste and texture of a rosketti recipe, however, produces a very distinct end result, due primarily to the use of cornstarch.

Rosketti dough is historically rolled into a log the size and length of a pencil.
