Meanwhile, fry the onions in plenty of oil until they’re soft and translucent, about 10 minutes, they should squidge flat between your fingers when they’re ready. Turn the heat up a little and cook the onions until they’re dark reddish brown, then add the garlic and cook for a minute. Add the miso and stir, then add the wine and bring to a simmer. Add 200ml water and the beef consommé and bring back to a simmer. Cook for 20 minutes, then season with black pepper and salt, if needed. Add a splash of water if the soup is too strong.
