Plenty of chips hiding under the curry ;D
Hi NJ
Totally agree with the problem of finding a good potato for chips, it really is pot luck most of the time.
Supermarket potatoes are the worst, the big three are terrible for any veg, IMO.
Aldi/Lidl are much better, but the most consistent are open markets and getting down to basics, the local independent corner shop.
These were the corner shop variety, the guy buys big sacks from the wholesale market
and bags them up into smaller plastic bags with the "Selected Potatoes" tag.
Pot luck on the variety, but these look like sorted chippers and all quite uniform in size. They did make excellent chips, double cooked as you said.
