In relation to what? In cookery, it's usually a term applied to meat - for example French trimmed (or cut) lamb chops - and relates to the way the chops are prepared during the butchery process and before cooking.
A french cut can be many things, in butchery terms...the french use a different system of cuts to us brits. Entrecote, mignon, and bavette are all french cuts in beef (ribeye, tenderloin and skirt are the british equivalents).
That's a bit of a misnomer, really! In france there's no 'french cut'...i'm presuming they just mean something cut on a jaunty angle! :os
There are french terms for the way vegetables are prepared, such as brunoise, julienne or chiffonade.
Calling something 'french cut' is really dumbing it down. Bloody NVQ-setters!!!
