Using an egg timer to brew black teas has really made a difference over just
wandering off for a while. (Electronic timers don't seem to fit the
aesthetic.) I've only found 3-minute timers in kitchen shops. Would really
like a 5-minute "hourglass" that I can mark for 3.5, 4 and 4.5 minutes.
Anybody know where to find such an item? Google didn't turn up a US source,
but I might have set the search too narrowly.

Thanks-
