Golden syrup and russet potatoes are your friend in this particular equation. They’ll unlock a bit more of an American style fry flavour for you. I think they use corn syrup in the states but golden is an acceptable substitute.Possibly against every grain of your being..... any tips on making French fries? I don't like potatoes.... so my chip of choice is the skinny option.
So far I've gone for Marris pipers, thinly cut and soaked in brine (water, sugar, salt & vinegar) overnight. Deep fried for 10 mins @ 150C and then deep fried for 2 mins at 200C.
They're OK.... but still not that fantastic fast food fry flavour that I'm after
ADDITIONAL - Add the syrup when you do your soak. You might have to play around with the quantities to find what works for you 👍
