Key ideas in The Science of the Perfect Fry
- Internal water turns into steam which softens the fry from the inside
- Sugar browns much faster than starch when exposed to heat
- Rapid browning on the surface happens before the heat reaches the center
- High water content prevents the surface from dehydrating into a crust
- Starch provides the structural 'fluff' inside a fry
- Russets have the low-water profile needed for frying
- Why high sugar content leads to a burnt taste
- Starch granules swell and burst to create a light, airy center
- Waxy potatoes hold their shape but stay moist and heavy
- The role of starch in creating internal structure
- The impact of water content on fry texture
- Comparing Russet and waxy potatoes for frying
- Surface dehydration must happen before a crust can form
- Internal steaming happens as the heat moves inward
- Low sugar prevents the fry from turning black too early
- High starch content ensures the fry has enough structure to stand up
