Celery

Use the same weight; slice the white and green parts and add a little later. It gives a milder oniony crunch rather than celery's bitter edge.

Use the same weight; chop finely and add as an aromatic. It gives a green, fresh note but no crunch.

Use the same weight; cut into thin strips and cook 2–3 minutes less. It provides crunch but is bland, so add a pinch of salt and a squeeze of lime.
