/ck/ - Food & Cooking

Ok please do not judge me for this but I did the worst thing imaginable, I bought a shitty €50 Krups espresso machine and some Lungo pods. I just have to say I am not a coffee purist, elitist or however you want to say it and that I have a simple question. The thing with the machine is that you manually put water in and it does not have any markings so you know how much you have to put in so as to get the best consistency. Manual does not give any other information.
How much water (in mL) should I put in and in what temperature? Not exactly, but should it just be room temperature tap water? I am not looking for anything luxurious, just a college student in need of some iced latte.
