Why Popcorn Actually Pops
- Popcorn pops because a hard hull traps steam until pressure ruptures it and the starchy interior foams out.
- The kernel's 14–20% moisture and oil content are crucial for that explosive transformation.
Flint Corn Is Popcorn's Ancestor
- Not all corn pops; flint corn has a hard hull and less soft starch, making it ideal for popcorn.
- Flint corn's multicolored kernels and cold resistance explain its deep historical cultivation.
How To Reduce Unpopped Kernels
- Heat kernels at an optimal rate to let the starch gelatinize before the hull bursts and avoid hard-centers.
- Re-moisturize old kernels to reduce the number of "old maids" that fail to pop.
