Do this
Put the minced aromatics into cold oil. Turn the heat to low. Wait until small bubbles form and the smell rises. That takes about one minute.
Why it works
Aroma compounds dissolve into fat, not water. Warming them in oil moves the smell into every drop of the sauce later.
When to skip it
Skip it when you want a fresh sharp bite. Raw grated garlic added at the end gives a completely different effect.
