I make root chips, crisp made fom parsnips and butterut squash. I have a food processor with a slicing accessory, but theres normally one on a grater too.
If you salt them first to help draw the moisture out, then either fry or bake them sprayed in oil, they come out yummy.
You sprinkle salt after removing them from the oil. If you salt the potatoes before frying they will release water and become soggy. Salt draws out water/liquid. Do not salt before frying.
I salt before and tissue paper them down to get the moisture out and mine are crisp everytime. We always used to eat breaded fried aubergine slices and you have to draw moisture out of them. The same with a butternut squash it would turn to gunge inside if you didnt. Potato is a dfferent story.
Desiree, Estima (baking spuds) would be good for home made crisps but if you can get them Golden Wonder of course will make the best crisps. You dont want them to floury and you dont want them to waxy else your crisps will be soggy.
