Here’s the cool part: cornstarch is made up of tiny, tightly packed starch granules. When you mix them with cold liquid, they just sort of float around, doing nothing special.
But add heat, and those granules start to swell and burst open. It’s like they’re throwing a microscopic pool party, soaking up all the liquid around them and locking it in place.
The result? That thin, watery sauce transforms into a silky, glossy gravy or a perfect pie filling. It’s basically physics you can eat—how cool is that?
Flour vs. Cornstarch: The Showdown
So, you’re probably thinking, “Why not just use regular flour?” Well, friend, they aren't the same thing at all. Flour is made from wheat and contains gluten, which can make your sauces look cloudy and feel a bit heavy.
Cornstarch, on the other hand, is pure starch. It makes things clear and shiny. Think of the difference between a muddy pond and a glossy lake.
If you want a sauce that looks like restaurant-quality glass, cornstarch is your go-to. Flour is for rustic, hearty stews; cornstarch is for elegant, delicate sauces.
