Pulse it for a few seconds, check the grind, then pulse again if needed. You're aiming for a uniform grind size. For a coarse grind, think French press, pulse for about 10 seconds . For a finer grind, like for espresso, you might go up to 20 seconds. Just keep an eye on it – over-grinding can lead to bitter coffee.
