here's my onion soup, in case anyone is interested. I went from bits of several recipes I found online, and it turned out pretty damn good.
4 lg white onions
3 md yellow onions
6 cloves garlic
2 clusters celery
dried thyme
salt
black pepper
100ml balsamic vinegar
200ml marsala
olive oil
butter
3 heaping tablespoons of flour
2 beef stock cubes
water
onions, olive oil, butter, salt, in pot, sweat onions 2-3 hrs
add celery, then garlic as ready, lots of pepper
stock cubes in water in separate pot, add thyme and pepper and boil down
sweat onions down to thick mixture, add vinegar/marsala and simmer
dust mixture with flour, stir well
add stock to mixture
add water, boil down to taste
