I am making Julia Child's Beef Bourguignon tonight and in the recipe she does this thing where you fry and stick in an onion at the start (pre the 4 hours of slow cooking) and then at the end you have to cook up a load more shallots (or small onions) and stick them in.
Why is that?
Is it just to make the dish more oniony, or does something happen to onion no1 during the slow cooking that means you need the added oomph of onions no 2 at the end?
Just wondering really. I've never had to do such a thing before.
