My question is, can I also use liquid lecithin in home-made non-stick pan coating? Also . . . << . . although I don't understand the need to add a non-stick substance to a non-stick pan . . >> There are some ingredients which will stick badly to non-stick surfaces. I make gulten-free waffles with Bob's Red Mill Gluten-Free Biscuit and Baking Mix, and if you don't season the non-stick waffle iron you're going to have major sticking problems which require a difficult clean-up, given the shape of waffle irons. I prep the surface with 1) leaf lard when the iron is new and occasionally later on (do not use Armour brand), and 2) sunflower oil. Then I brush on sunflower oil before every use, and still there are some serious sticking problems. This is bothersome because a lot of oil must be used, I don't like the wastefulness esp since I buy high quality sunflower oil (La Tourangelle and Rapunzel). I just started using Pam, and it absolutely works wonders, causing zero sticking. So if you're using gluten-free flour, Pam is the answer . . . but I'm going to try the home-made non-stick because I dont' care for Pam's petrochemical ingredients. Finally, as someone pointed out to me years ago on eGullet, cast iron seasoned with real leaf lard is far and away the least-sticky surface. For years I seasoned cast iron with oils until one day I tried leaf lard, and the difference is enormous.
