How to Make One of MY Coffees




This is my first Instructable so be nice damn it.

Right, if you have caffeine sensitivity, are pregnant or on any medication that is not suitable for use with caffeine I would advise against drinking one of these.

This makes about 1L (one litre) of finished coffee. It is strong and will give you more than a perk. It contains about 200mg caffeine which is a fifth of a lethal dose you have been warned.

Step 1: Getting the Equiptment...

The tools:
A smoothie maker is best but a blender would work as well.
A teaspoon.
A jug or bottle for the finished product.

The ingrediants:
Sugar or sweetener to taste.
About one litre of milk.
About 10 teaspoons of instant coffee granules.

First things first, measure out the coffee. I use 10 teaspoons, add more or less if you wish. Then add the sugar or sweetener to taste.

Step 2: Making It Smooth.

Once you have the instant coffee and sugar/sweetener in the blender/smoothie-maker I would advise sealing it and switching it on for a minute or two to powder and blend the ingredients.

Step 3: Add Milk

Add about 1L (One Litre) of cold, fresh milk to the blender ON TOP OF THE SOLID MIXTURE.

That will ensure a smoother, more even mix.

Step 4: Blitz...

Blitz the mixture for 2-3 minutes on a HIGH SETTING. This will ensure it is smooth and doesn't have solid granules of coffee.

Step 5: Serve and Enjoy.

Now it is ready to be enjoyed. Alter the recipe, add a new twist, be creative with it.

    Instant? Milk?? Sweetener?!?! Ye be a heathen!

    How about a cup of MY coffee? I used to drink it when I lived 60 miles from my place of work (I went 6 months without seeing daylight in my "home" town, except for Sundays). It's best prepared at around 5am.

    You need - a litre-size thermos flask. Roast ground coffee of your choice (my preference is a strong dark-roasted arabica). Ground nutmeg.

    Put two large tablespoons ground coffee in the flask, add a pinch of nutmeg and top up with freshly-boiled water. Close flask and place in footwell of car.

    Drive through dawn.

    Stand flask up and allow to rest for a couple of minutes (the grounds will by now be fully-saturated, and sink to the bottom of the flask).

    Open, carefully pour out a cup-full, drink and WHAM!

    "Hai-yah!" *makes ninja gestures at you*

    I took akimbo once, but my sensai kicked me out for telling too many "stupid" Chuck Norris jokes. Sadly, Chuck would later find out about this and kill the sensai for heresy. ;)

    (Sorry, must be all the caffeine...)

    So I'm not the only one that pours boiling water right over the coffee grounds in the flask. That's my road-trip coffee for my infamous 2-a.m. drives across two states.

    I just made one of these, the taste is pretty damn nice, only issue you may want to remind people that they need a good bit more than a liter of space in their blender, it foams up a little and doing it in my 1.3l I had to split it into two halves to avoid spilling over. Also, just as I put this on the track 1/4th the lethal dose came on, so I was narratively obligated to add a little more coffee.

    I think, but don't quote me, that 200mg is a fifth the LD50 which means a fifth of the dose that kills 1/2 (50 percent) of people.
    Although I thought the LD50 was 1.2mg, so it would be 1/6'th the LD50.
    Ohwell, just nitpicking.

    The LD50 is 192 mg/kg in rats so based on the rats I weighing 145lbs would have to ingest 12.6mg((145lbs to 65.8kg)*0.192g) of caffeine to reach the LD50 not counting any tolerance to caffeine I may have. Which works out to about the correct range the lowest well documented caffeine death was 10g and the highest documented survival was 20g. So in summery 200mg is nothing to your average habituated caffeine addict.

    And as a added rider in case anyone thinks that gives them leeway to ingest more than a gram of caffeine thats the LD50, not when you start to get sick, I assure you that any thing over a gram will be most unpleasant unless you have a substantial tolerance built up.

    Well, then. I was able to consume about 1.5g of caffeine over the course of a night once, feeling nothing. This was through caffeine tablets, Black Pearl energy drinks, and Mountain Dew. I seriously took a nap, even. I think I was a bit hung over or something, though after I woke up in the morning.

    its rather easy to build up tolerance with out realizing it. I have personally consumed over 2g, and passed out the second I got in bed, but that was at my worst when I was going threw 1/2 a pot of coffee, 2 cans of jolt, and a 6 pack of mountain dew a day. If you don't have a tolerance built up it doesn't take much to mess up your digestive system, dehydrate you(it makes you piss, even the pills), give you a migraine. Nothing terribly life threatening but by no means fun.

    From the energyfiend page on instant coffee: "According to the USDA*, 1 rounded teaspoon of instant coffee (1.8 mg) contains 57 mg of caffeine. No matter how much water, milk, or creamer you add to the coffee - the amount of caffeine will remain the same."
    If that is the case, and you are using 10 teaspoons, and rounding them, this is actually something like 570 mg of caffeine! You might want to mark this Instructable as "Not liable". :-)

    You can compare this with other drinks at energyfiend's caffeine database. For example, I now know that the double-shot espresso I'm so fond of contains about 400 mg (the places I go serve a 2 oz. shot instead of the 1.5 oz they list.) They also have a calculator to determine how much of a given drink you need to consume in order to kill yourself, based on your body weight. (I need 141 shots of 1.5 oz. espresso, or 102 real shots, all at once.) For most of the drinks, you would die of a ruptured bladder from drinking so much before you would die of caffeine overdose.
