You get a rough surface on the spuds with a rumbler plus it does not get the skin off fully there are bits left in the 'creases' that have to be removed by hand anyway. There are catering suppliers who deliver sacks of peeled spuds and most places use them, but the spuds are peeled with a knife.
Jackdaw triple cooked chips are the only way to go. Cut into chips, boil for a few mins (In the pro kitchen we steam them in an oven rather than boil)
Then cool and dry them ,( in the pro kitchen we turn off the steam and dry them in the oven then cool them)
Then 'blanch' in deep fat fryer at 140 deg C , drain and finally brown them in the deep fat fryer at 185 deg C. >> = Perfect chips, crisp on the outside and soft on the inside. We have 4, 50 liter deep fat fryers just for chips and they are filtered after every service and drained and refilled with new oil once a week (guess who gets that job?)
