Here's the basic instructions:
Slice the lemons and onions. I used 3 lemons and 2 onions - one red and one white.

I found these half gallon jars at the dollar store last year.

Add a layer of lemon, then onion, then lemon, etc. And pour the honey over them. I used about 20 ounces of honey.

Then top it off with the schnapps and the brandy. I used more brandy than schnapps, but some recipes call for equal amounts and others call for more schnapps.

I think adding some ginger would be a good idea, so I may try that. This stuff is suppose to last around a year if sealed tightly and stored in a cool place.
After letting it sit in the pantry for a week, it taste just like real cough syrup. The first time I tasted it, a few days after making it, the onion was a bit too strong. But now I don't notice it. I personally think we should not try to suppress coughing because it's the body's way of dealing with toxins that need to be removed, but sometimes you need a little break from the coughing. Like at night, so you can sleep.
According to the recipes, the recommended dosage is 1 Tablespoon for adults, and 1/4 teaspoon for children. I'm not a mommy or a doctor, so I can't say if that is a good recommendation or not. But one tablespoon seems to do the trick for me.
