Roast potatoes will be crispy with no pale patches if sprayed with a simple item
Anyone who has ever made roast potatoes knows they can be a gamble; sometimes they come out perfectly golden brown while other times they turn out pale and soggy. It can be frustrating as roast potatoes are usually the best part of any dinner, but they can turn out limp if there is too much moisture on the tray while they are cooking. Potatoes naturally contain a lot of water, which turns into steam during the roasting process, and if the skin stays wet, then you will end up with colourless and mushy spuds.

TL;DR
- Spraying roast potatoes with a small amount of vinegar during cooking can help them crisp up and develop a deeper flavor without tasting vinegary.
- Vinegar's acetic acid reacts with pectin, improving the potato's structure and enhancing the crust for a crunchier skin.
- Using fats with a high smoke point (vegetable, duck, or goose fat) is essential for achieving crispy roast potatoes, as low-smoke oils like olive oil can lead to sogginess.
- Proper preparation includes parboiling, draining, steam-drying for five minutes, and gently shaking the potatoes to roughen their surfaces for better crust formation.
