Five Guys Fries

Russet potatoes
sea salt
100% peanut oil, for frying

Cut the potatoes into fries and then soak in ice-cold water until
the water runs completely clear.  You will have to drain the water
and add more cold water a few times to achieve this.  This will
wash away the excess starches.

Set your deep fryer to 345-350 degrees F.

Drop some of your fries into the fryer until they turn a very light
brown.  Remove from fryer and let them rest for at least 5-10
minutes.

After they have rested, fry them a second time to your desired
doneness.

Season with sea salt.

For Cajun fries, dust the fries with a Cajun spice blend.
