Toasting whole cumin makes it smell stronger and taste rounder than raw.

The one thing you change: Toasted or not

You need

Steps

Split the seeds in half. Leave one half raw.
Toast the other half in a dry pan on medium for 1 to 2 minutes, shaking, until it smells strong. Let it cool.

What you should find

The toasted one smells deeper and tastes nuttier. The raw one is sharper and a bit dusty.
