How to get delicious and crispy potato wedges?

[Bes]

Hi,

I am going to try my hand at some potato wedges tomorrow.

Usually when I make them, the result is something that is lacking crunch and a crisp exterior. My usual method is:

Slice potatoes
Part- boil (10 mins or less)
coat in olive oil, pepper, and a decent amount of salt
Cook in the oven as hot as possible until ready

Any tips to improve? I have heard using goose fat can work well, anything else I should consider?

Thanks

With baked potatoes I stab the skin all over with a fork and rub in oil and salt by hand. I'm sure a similar method would work for wedges!

Edit: Why boil?

Otherwise the potatoes will burn on the outside before they cook on the inside I think. Also it is supposed to make the surface of the potato crispen up better.
