/ck/ - Food & Cooking

Well /ck/, you finally did it! You managed to bring a girl home for (what you hoped was) sexy times. The night was miraculous, and she was willing to stay over 'til morning. You wake up ahead of her, and decide this would be an ample opportunity to make her a cup of coffee -- and a special cup at that. You improvise with what you have in that kitchen, and worked any magic you could.

The coffee is ready, and lo and behold! She wakes up in time for you to deliver it to her. She's flattered by the gesture, and gives you the same flirtatious eyes and luscious smile that won your heart the previous night. You chat like you've known each other for years, and then she takes her first sip... something is wrong... she swishes the coffee in her mouth to get a better gauge of the flavour, and looks in the cup with the most puzzled face you've seen on a woman (she even makes crunching motions with her jaw). She then looks into your eyes, just as puzzled, but with concern now mixed into her expression

What did you put in the coffee that's distressing the lady, /ck/?
