As I'd blogged about it recently I picked up a vindaloo rather than my traditional dhansak for the first time in years.
When I tasted the potato in it, I remembered something that I'd read in Wikipedia:
Restaurants often serve this dish with chicken or lamb sometimes mixed with potatoes. Traditional vindaloos do not include potatoes, the discrepancy arising because the word 'aloo' meaning garlic (presumably derived from the Portuguese word 'alho') is mistranslated as 'potato' as it is in Hindi.
Isn't that great?
