This is an easy weeknight dinner. I came up with it because I wanted a lighter version of the classic comfort soup.

Why does raw broccoli turn an olive-drab color while canned vegetables hold a dull gray-green? Fresh plant cells contain chlorophyll, which degrades into pheophytin when exposed to heat and the natural acids released during cellular rupture. Sautéing the brassica briefly in oil coats the exterior, slowing moisture loss before the long braise.
Cornstarch relies on gelatinization, requiring liquid absorption and thermal energy around 203 degrees Fahrenheit to swell its amylose chains and thicken the broth. Adding cheese too early causes the milk proteins to clump into a grainy mass instead of emulsifying smoothly into the stock. Whisking the cornstarch thoroughly into the cold stock before heating prevents lumps from forming around the seasonings.
