I have a porlex mini, set it to as course as I can so that it's still pretty uniform. Fill the beans holder to the top (about 20g). Grind. Aeropress inverted, rinsed paper filter. Put grinds into aeropress. Pour about 40g boiled water into cup - this preheats the cup and cools the water slightly, swirl til the cup warms. Pour the 'cooled' water into the grinds and swirl /stir for about 15 seconds. Fill aeropress with boiled water, put in cap+filter, put on cup and press - full press should be around 30 seconds. Top up cup with boiled water if you want.
