When I brew my coffee, I generally do it in 4 parts. One is the blooming phase, I pour 50ml and wait until it's all gone through.
Then I do three other 50ml pours with 10 seconds between each.

To count these 10 seconds, I use crocodiles, like so: "Un crocodile, deux crocodiles, trois crocodiles,...".

Crocodile is the word we use in the french speaking part of Belgium. I think I have seen Americans use Mississippi as well.

I'll use this note as a way to compile all different manners of counting in seconds from around the world. If you could send me an email to tell me how it's done in your part of the world, I'd be very pleased.
