Thanks.
The pictures on the grill had one tray two-thirds cooked the back one was raw and had just been placed on so when finished most pieces were darker with some a little charred.
We both thought it tasted identical to the satay we have in Singapore except that my pieces of meat were fatter, juicier, tastier and of a nicer texture. I prefer them being fatter. I did that because my kitchen lava grill is going to not be as hot as my charcoal bbq and I didn't want it to dry. I didn't add too much turmeric because I didn't want to increase the earthy taste.
To be honest it tasted perfect although I can't be bothered to make the peanut sauce but the bought one was anaemic. I'm going to find a better one.
