Why are some fries Brown?
When potato strips are dropped into hot oil, the sudden high heat turns moisture near the potatoes’ surface into steam, which pushes outward, causing bubbles and that familiar sizzle. In contrast, fries made with lower-starch/higher-moisture potatoes get brown before they lose all their moisture.
Why are some potato chips brown?
The cold temperatures needed for long-term storage of potatoes cause the starch in spuds to break down into smaller sugar molecules. It’s the reaction between these sugars and the extreme heat of deep frying that causes browning.
Why do potatoes brown when they are fried in oil but not when they are boiled in water?
Oil is hot enough for the Maillard reaction to take place and for the potatoes to brown (slightly). The heat and speed give a good contrast between crunchy & moist.
