Ground coffee in a french press. Pour half full of water, stir, pour again. Leave the lid off for 4 minutes, then remove the scum from the top with a spoon and press. Gets me 3 large cups that I drink with (cow-) milk until pooptime. I’d use beans here, but my wife keeps the free bags of ground coffee flowing (for reasons I cannot share) and the results are still pretty good.
If I need more coffee after this, I’ll use a Philips espresso machine to make either a café latte, cafe au lait or sometimes iced coffee. I use oat milk for the latte/au lait so I can use the milk foam thingie for longer without cleaning it. At the moment I have a few mixed bags of beans brought from Kenya, so that’s nice. Otherwise beans from the supermarket.
The water here is very hard, so I use filtered water.
