well, I often do "cupboard' brews - kinda mix what I have in my garage.
As for your stuff - it will make really nice beer - do the prep, sanitize stuff/ect, boil 1 gallon (I think its somewhat close to 2.2liters) of water, have kettle with boiling water ready - toss your 2 pounds of muntons into fermenter, add galon of boiling water, swirl it around to dissolve malt extract, add heated coopers can, fill it with boiling water from kettle, swirl to get it all out, toss into fermenter, stir vigorously, top it to 23l (6us gallons?) of cool water, if you can, try make a "waterfall" to aerate the wort. pitch yeast if your temp is within 68-80F range, stir it a bit and that would be it.
leave corn sugar for priming!
balls, if 1us gallon is about 3.5 liters, then make your boiling water to half gallon! its soooooo confusing leaving the "normal" metric world!
