Beside the convenience of machine-brewed coffee I found the aeropress to be an extremly forgiving brewer. I can’t remember ever making bad coffee with it (though I’m a taste barbarian, I enjoy strong flavors, but fine nuances are lost to me, so YMMV). As such my “recipe” is dirt-simple an can be done before having coffee (that circular dependency is always a problem with other methods).
I have that Fellow Prismo thingie, so need to mess around with brewing inverted
I usually add a paper filter to the metal filter, but more for cleanup reasons than taste
15g beans, finely ground but not quite espresso-fine
Quickly add 100ish grams of boiling water
stirr
fill up to 250g water total
put on the plunger
wait about 2-3 minutes, plunge & enjoy
For my friend, or if I’m feeling the occasionly sweet tooth myself, I do basically the same just with 125g total water (can be added in one go, I only stirr after 100 above as it is easier and less prone to make a mess if you are too vigorous) The “missing” 125g of water are then replaced with 125g of milk (or a milk-replacement of your choice) + 5g (or 10 for the espially sweet toothed) sugar that receive the nanofoamer treatment
But as I said the Aeropress is extremly forgiving, you can diverge from the recipe quite a bit and still get good coffee. Sometimes I’m distracted and only come back to plunge after 8 minutes and the coffee is still good. Spoon was too full and now its 16g? No need to pick beans out of the grinder, that’ll work too. If you have a feeling for measurements (I don’t) you can just eyball that stuff and not sweat the details
