A while back I was searching for some info for a European friend in an Australian published Cookbook and I found a"useful information page" and one topic was Oven Temps. It gave oven temps for both gas and electric, but only when the temp hits the mod hot level does it list the two; i.e.190 (Gas)-210 (elec).
The proviso listed is that the flame in gas generates a drier heat which cooks faster than a moister heat of an electric even if the temp setting is the same. However, I recall reading somewhere that the burning of gas in an enclosed area like an oven produces a moister heat than electric which is why Bread is better baked in an electric oven. I will do some digging to verify that but if someone already knows the answer perhaps they will share. Meantime here is the chart, hope it helps you
very slow 120C , 250 f, gasmark 1/2 slow 150C, 300f, gasmark 2 mod slow 160C, 325f, gasmark 3 moderate 180C , 350f, gasmark 4 Mod Hot 190(G)- 210(e) C, 375-415f, gasmark 5 Hot 200 (g)-240(e)C, 400-475f, gasmark 6 very Hot 230(g)-260(e) C, 450-525f, gasmark 8
"A knob allows me to adjust the size of the flame and that's it. I know this is almost prehistoric by first world standards, but it's normal here."
just curious. do you have gasmarks like the Europeans do?
