Secret to Dunkin Donuts Coffee

For months I tried to duplicate the taste
of Dunkin Donuts coffee at home.
The coffee beans they use are delivered
inside silver vacuum sealed bags.
Was I missing a secret ingredient!
For starters, you must grind
the beans just before brewing.
Make sure the water you’re using
to brew is Cold. Really cold.
Lastly, the secret ingredient,
actually, ingredients.
Put one tablespoon of marsala wine
for each cup of coffee, and
one tablespoon of vanilla extract
per full pot of coffee. Enjoy!!
