Empty a can of Medaglia d’Oro coffee into a large bowl.
Then, fill that now-emptied Medaglia d’Oro coffee can with your favourite drip coffee. Pack lightly.
Add that to the bowl and using your hands, mix and blend well.
Store in a large (925g / 32 oz) empty coffee can.
Per K-Cup, use 1 generously heaped tablespoon (about 5 ½ teaspoons / 2 scant tablespoons.)
Do not press down too tightly on the coffee in the K-Cup filter -- the secret is to allow the hot water room to swirl around in the coffee as it passes through the filter. Do not fill the K-Cup completely full; the coffee needs room to swell as the hot water hits it.
For the regular coffee, you could also use decaf, to reduce the caffeine if desired.
