I'm pretty sure this is her recipe! Anyhow, this was the best batch yet - must have been the combination of ingredients for the broth, but whatever it was, I was feeling euphoric upon consumption - better than 'oh, the risotto'!
4 large onions
1/3 cup olive oil
6 cups beef stock
good glug of sherry (I used Madeira)
1/4 cup butter
1 tsp sugar
2 cloves garlic
dash cayenne
3/4 tsp instant coffee (mom's secret ingredient)
dash dry mustard (I never have any, so used a blob of dijon)
Parmesan cheese
good bread
Swiss cheese (I used Gruyere)
Heat olive oil on med heat - add onions - saute, stirring often until transparent. Add butter, along with minced garlic, and continue cooking until onion is limp.
In the meantime, heat your stock in a separate pot. Add sugar, cayenne, booze, coffee, mustard, s & p if desired. You'll know what to tweak to your particular taste.
Ladle soup into bowls. Another quick timesaver, is to heat your bread slices in the oven, add slices of cheese on top, heat, then broil - and cut bread into chunks then serve directly onto soup (in lieu of serving in onion soup bowls (which are notoriously small), then adding whole slices and heating in the oven, then struggling with the cheesy bits!); then top with a dusting of Parmesan. This soup will make you weep with joy - trust.
