I know I've stepped back from this challenge already, but our team needs another one who does it, so I thought hard how to manage it. And I remembered that many years ago, DH purchased a one-way-grill which we wanted to use for a day-trip by bicycle. We never did it, and that thing still sat in the basement waiting for use.
It's a thingy like this one: https://www.amazon.de/Activa-10050-Einweggrill/dp/B006J3RIPW/ref=sr_1_9?ie=UTF8&qid=1472130645&sr=8-9&keywords=Einmalgrill
We found it in the Netherlands, back then, and now I used it to make diner's http://www.justapinch.com/recipes/main-course/main-course-chicken/chicken-souvlaki-kebabs.html?p=1
It did work - a very rustic method, but with fire and charcoal.
The grill had a firing agent which I did not use because I don't trust that stuff... don't want it near my food. So I heated the charcoal in the small clay oven which we have on the terrace (which usually is for warming when it's a bit cool outside), then got it out with the small shovel we usually use for our fireplace inside the house, and put the charcoal into the grill thingy (sorry - I don't know how this aluminum pan is called in English!), covered it with the oiled grate (a *very* fragile thing, but it worked), waited until I thought the heat was low enough so that the meat would not burn immediately (the charcoal is very, very close to the grate and the meat) and then went ahead and grilled the meat like the recipe description says.
I have to say that it does taste quite smokey with this kind if grill, but I also have to admit that I am totally new to grilling. usually DH was our grill-master, but since he's ill, he doesn't do it, so I tried it and dan honestly say it was a very exciting experience
For heating the charcoal, I burned some paper and wood shavings, then put the charcoal on top and waited until it was red hot.
When I looked for the picture of the grill online, I found it on amazon with some quite enthusiastic reviews and comments, but I have to say that it really is more kind of a makeshift. But it definitely gets meat done, and it is fun, and it's authentic because it's grilling on real fire ;-)
I had a lot of fun doing this.
