I use olive oil a lot but if I am going to sautee meat and need a lot of heat I will use something like groundnut or rapeseed which has a neutral flavour and a much higher smoke point. Olive oil starts to burn at about 190c
I sometimes use toasted sesame oil in oriental cooking for flavour and for making curries I use ghee.
Olive oil and balsamic make a great foccacia "dip". - LouBelle
