I found a thick-walled plastic cup I hadn’t used for a few years. It has a vertical channel in the inside & a filter attachment that slides down the channel to hold used coffee grounds or tea leaves at the bottom of the cup in a similar manner to a French press plunger. Brew up, plunge down, add milk/sugar/honey/cream to taste.

@peemee Nice! How well does it work?

@KyleL Very well, you can see some coffee grounds on to of the filter from my last brew. That’s because I used a fine espresso grind instead of a coarse French press grind. Being thick-walled means it keeps the contents nicely hot, too.
