Coffee. The Dunkin Donuts brand coffee. The best simple coffee to brew ever! I don't buy that overprice milk and sugar bullshit at Starbucks. Starbucks is so stupid. If anybody just winging it with their brand of Coffee, let me tell you something. Stop what you are doing. Drive over to Target and pick up a Orignal Dunkin Donut Coffee bag off the shelve and purchase it, take it home, brew it and drink it.
