emin-j,
i can't work out what it is that happens with the extra heat. all i can add is that if there is no smoke then i don't get the different taste. when i get a lot of smoke i get the taste difference.
Haldi,
all i can add is that i have really tried to get the same result with low heat and failed.
the big burner does for sure give the speed and ability to incinerate everything. it took me quite a while to master it - in fact it needed real perseverance to find the difference (read the link in the earlier post).
cooking in the garage is quite a hassle (the trip round the house with a tray of ingredients etc) but honestly i won't be moving the cooking back to low heat.
et al,
it's not worth going round the discussion on this one. you need to make up your own mind on whether it's worth it to you. all i can say is the stove at ?30 is the best thing i've bought in probably my life. look at the extract in your TA - if there is no smoke going up the stack then stick with what you use at the moment.
