Soak the potatoes in salt water
First of all, add about eight cups of water in a large bowl and add about ¼ cup of salt to it. Stir the mixture of water and salt nicely until they are well combined. Now add the thinly cut potatoes into the bowl and stir the water slowly. Leave the potatoes in the bowl for at least 20 minutes so that the mixture gets soaked into the potatoes. After 20 minutes, remove the potatoes from the bowl and dry them with the help of paper towels.
Prepare the powder in a spice grinder
Add the buttermilk powder, onion powder, sugar, garlic powder, dill and the remaining one teaspoon salt into a spice grinder and grind the ingredients for a few minutes.
Fry the potatoes
Add the potatoes to a heated Dutch oven and fry them until they reach a golden brown colour. The process may take about two or three minutes.
Sprinkle the powder
After the potatoes are fried, place them on a baking sheet and sprinkle the powder on them. Mix the chips nicely after adding some more powder.
Keep the chips in a container
Place the chips in a semi-airtight container for a few days so that they become crispier. Keeping chips aside for a few days will give you best results.
