I have found a spell in the freezer works really well with roast spuds but I can’t get chips quite the same double cooking them. It seems to me that the boiling stage is very important too, you need them to develop fissures. The ones pictured were the best I have done but I think I can get them better and the boiling stage is the bit I need to concentrate on - I always bottle out of leaving them a couple of more minutes!
As Richie says, you need the chips to develop fissures. I find that cooking them through, then tipping from pan to collander breaks them up enough to get lots of rough edges. These edges crisp up (if sufficiently dried out, hence fridge time) in the hot oil.
I’ll take a photo of mine next time. Everyone tells me I make the best chips they’ve ever had, but honestly it’s no great secret or skill. Just roast spud method.
I put them into the freezer for an hour after boiling and an hour after the first fry, forgot to mention. I can see how I can improve them but repetition means my trousers don’t fit!
On sous vide machines, do we think there is much difference between them? There are much cheaper ones than the Anova, but I wonder if they are as good…
I don’t have any experience with other machines and only have a little experience with the Anova but it is a very solid bit of kit and works well. I bought it because one of my colleagues has one and she bought it because a friend of her’s has one… I guess it must have a reputation for being reliable.
