its kinda hit or miss with onions and really hard on heartier vegs like carrots. how do you sweat your veggies? i know low heat..i've done this but i usually find them showing a little char after 5 minutes. i wonder if i shouldn't stir the veggies when i throw them in there at first. i have a feeling that stirring them reduces the amount of oil in contact with the food and pan. does this cause burning. should i possibly use more oil or how about an oil with a lower smoke point than extra virgin olive.
