I have a couple of related questions about a couple of the passages that could be potentially confusing or misleading.
First, "et mélangez-la avec l'oignon et l'ail finement hachés," ... it's clear in writing, but not necessarily in speech, that "finely chopped" refers to both the onion & the garlic.
Secondly, "le thym, le persil, l'ognon pays et une pincée de sel et de poivre.": I looked this up on the web, & apparently the "pinch of" refers to both the salt and the pepper. So, how do you know that? Because, would "a pinch of salt & some pepper" be expressed "une pincée de sel et du poivre"?
