Yes, it& spicy. Lamb vindaoo is a spicy Indian stew and a favorite in most curry houses, where you& often find it with added potatoes. No potatoes here my friend just tangy, spiced lamb marinaded and cooked to perfection.
several times a year, i just make a gallon of this stuff and then live off of it for a couple of weeks. which is kind of weird, because it's so easy to make even on a daily basis. at least the sauce is.
