Some of you asked how much 500 g is — I recommend you to use one of the many excellent convertsions calculators online, for example http://www.worldwidemetric.com/metcal.html. But you won't need it to make my müsli as I'm more than vague regarding both measurements and ingredients!
Living as I do in a small town, I have to use whatever ingredients I can find. There is a mix of rye, wheat, oats and barley flakes that I like to use, but I can't get it where I live so usually make a blend of rye (more rye than anything else because I like the taste of it), spelt and oats — not too much oats.
I toast the cereal in the oven and mix it with toasted almonds, nuts and seeds and dried fruit. In the fall I dry my own apples and pears but other than that I use what I have.
That's all. It takes some time as I cut the fruit and chop the nuts. Go ahead Ellen! You have most of the ingredients within a block or two and don't even have to get your car out to go shopping!
