Eleven minutes is a slightly generous ten: the extra minute is for finding your place, not for a new task. Musicians can run a short piece twice with a breath between takes.
In a kitchen, eleven minutes is a sauce you reduce while you stay at the stove. Press space to start or pause, R to reset, and F for fullscreen. The screen can stay awake after you start, using the wake lock your browser allows. Pick the alarm before you begin. A bell, a chime, a beep, or a short digital pulse all come from the Web Audio API, so there is no sound file to wait on.
This page is the 11 minutes countdown and nothing else is running underneath it. Related lengths are linked under the guide if you want a neighbor, and the timer itself stays above the fold.
