This is definately the best samosa making technique, it's foolproof with superb results.
I've have been accused of buying them before now, they turn out so good friends don't believe I made them. They're far better than my local TA or anything you can get in a shop.
Anyone who's not attempted them is missing out. First time making them seems a bit laborious but once you get the hang of it and done it a few times you'll be flying and experimenting with different fillings.
I make these regularly and can knock out 2 dozen in no time these days.
Chicken curry and beef vindaloo fillings always go down a storm.

will post some pics next time I make some (probably this weekend)
