One suggestion - in Step 7 (add more liquid), I'd add some sherry...
cream sherry if the onions aren't very sweet, dry sherry if they are sweet.
caramelized onion
cream ingredients: 1 tbsp oil + extra
if needed 1 medium cooking onion, sliced into thin half moons 1 - 2 sprigs of thyme, leaves chopped (optional) 1 - 2 cloves of garlic, sliced big splash of
sherry vinegar salt + pepper 1 can of full fat coconut milk, chilled overnight
