How tempering chocolate keeps it shiny

Tempering leaves cocoa butter set in its stable, glossy crystal.

When the purchase is complete, return to the original window. It will refresh.

From the opening

Tempering keeps chocolate shiny because it steers cocoa butter into a stable crystal form as it sets. That form is dense and smooth at the surface, so light reflects and the bar snaps, instead of setting as a dull mix of unstable crystals. The opening covers cocoa butter has several crystals, stable seeds guide the set, and milk fat shifts the window.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
