Lecithin

QUESTION FROM EMILY: I was wondering about an additive, such as granular lecithin, which you would add to cookies and scones to improve shelf life? Is there such a thing? Thanks, Emily Veale ( I have the Cake and Bread Bibles WONDERFUL!!)

ROSE REPLY: the king arthur catalogue sells granular lecithin that they claim is "shelf-stable" and the liquid lecithin is available in health food stores. it is a soy product that becomes rancid very quicly so i store any lecithin product in the refrigerater. you will have to experiment with amounts and it does indeed improve shelf-life but can also give an off flavor to the baked goods if used in excess.
