Food Facts
Sourced notes. Tap to verify.
A lot of dairy texture comes from milk proteins like casein. When those proteins coagulate (from acid, heat, or enzymes), you get curds, thickeners, and the backbone of cheeses and creamy sauces.
Water and mechanical work align wheat proteins into a gluten network that traps gas and determines chew, rise, and structure in doughs.

Cool fact: If your bananas are yellow, bake them (in the skin) at 300°F for 15 minutes until black. It mimics the aging process.
Bread is dense/gummy at the bottom.
You overmixed the batter, or the bananas were too large (too much liquid).
Burnt outside, raw middle.
Cover loosely with foil for the last 20 minutes of baking.

The Mise en Place
4Your prep station before cooking begins
MASH
MASH bananas (3 each) with a fork. Leave some chunks. Texture: Like chunky baby food, not a puree.
WHISK
Whisk butter (½ cups), sugar, eggs, and vanilla. Stir in sour cream (½ cups).
FOLD
Fold in dry ingredients. Pitfall: Do not overmix. If you develop gluten here, you get a rubbery loaf. Stop when you see the last streak of flour.
BAKE
BAKE at 350°F (175°C) for 60 minutes.
The "Crack Test." The top should split down the middle. A toothpick inserted should come out clean, but moist.
