>>21491647 (OP)>choose the right potatoes >soak in ice water >double fryYou can parboil in alkaline water but I feel like it's only useful if you can do giant batches in a pressure cooker otherwise it's too messy, never accurate and overall just a bit of a waste of time.
Oh yeah. On a home setup you really want thicker fries
Much more room for inaccuracies. Shoestring fries easily turn into garbage.
PS: If you have the aforementioned large pressure cooker then freezing your parboiled fries leads to God tier results.
Personally I mainly do it for hash browns because sourcing the right kind premade is really annoying here but it works for fries too.
