Thomas Jefferson's Macaroni Machine Design

Jefferson's macaroni machine

Jefferson's drawing of a macaroni machine and notes, courtesy US Library of Congress. Said the future second President in his notes, above: "The best maccaroni in Italy is made with a particular sort of flour called Semola, in Naples: but in almost every shop a different sort of flour is commonly used; for, provided the flour be of a good quality, & not ground extremely fine, it will always do very well. a paste is made with flour, water & less yeast than is used for making bread. this paste is then put, by little at a time, vir. about 5. or 6. tb each time into a round iron box ABC. the under part of which is perforated with holes, through which the paste, when pressed by the screw DEF, comes out, and forms the Maccaroni g.g.g. which, when sufficiently long, are cut & spread to dry. the screw is turned by a lever inserted into the hole K, of which there are 4. or 6. it is evident that on turning the screw one way, the cylindrical part F. which fits the iron box or mortar perfectly well, must press upon the paste and must force it out of the holes. LIM is a strong wooden frame, properly fast-ened to the wall, floor, and ceiling of the room. N.O. is a figure on a larger scale of some of the holes in the iron plate, where all the black is solid, and the rest open. the real plate has a great many holes, and is screwed to the box or mortar: or rather there is a set of plates which may be changed at will, with holes of different shapes & sizes for the different sorts of Maccaroni."

1) Please try the table of contents or the search box at the top of every page before you cry for help.

2) Try to post your question to the appropriate page.

3) Tell us everything we need to know to help such as the type of cooker and thermometer. Dial thermometers are often off by as much as 50°F so if you are not using a good digital thermometer we probably can't help you with time and temp questions. Please read this article about thermometers.

4) If you are a member of the Pitmaster Club, your comments login is probably different.
