Bought a reusable nespresso pod + silicone lid from AliExpress.
It works surprisingly well. Used some Peats pre-ground coffee from Costco that I'm trying to burn through. Crema was thick and taste was smooth and not over-extracted. Tasted like good diner coffee.
For whole beans, I'd dial the grind a bit on the coarser side because there's pinholes where the coffee comes out - the grind you'd use for a typical pour-over should be good enough.
Whole setup was like $10. The pod itself and the silicone lid are sold separately. You can use foil stickers for the top but that defeats the purpose of a reusable pod.
Pretty convenient when I don't have time to dig out the Aeropress or wait for the Vietnamese coffee phin to drip.
