I used this recipe this week and the results were great. I shall be using this recipe as my 'standard' vindaloo.
I didn't follow the recipe exactly, making these changes:
The end result was a dish that gleamed shinily, looked the business, had a lovely taste, hot. but not steaming hot and had 'body' which I think was due to the black cardamom. I like a wet curry so I increased the quantities of the sauce ingredients.
The heat comes from black peppercorns and the dried chillies. This i find, means it lacks the flavour of chillies which I understand why - this dish was used to preserve meat on long ocean voyages by the Portugese.
I'd like to ask listers if they have a recipe that delivers a heat similar to Madras or Vindaloo, but which also delivers the flavour of fresh chillies.
Looking forward to hearing from the list,
Martin
