Wow - I;ve never seen a recipe that calls for either... what are you making? I would probably try a health food store for the lecithin, not sure about the xanthan gum.
If your local grocery store has a health food aisle you may be able to find xanthan/guar gum and lecithin there. If not, a health food store should carry all of them. Al
What are you making? I use Xanthan Gum in my gluten-free treats and lecithin for wheat breads. Neither go "bad". I buy a lot of stuff from Barry Farm Foods (barryfarm.com), in bulk, since I bake every week most all year for farmers market offerings. Smaller packaging cost an arm and a leg at local stores. So, the question is how much will you be using - bulk vs. price.
Along with the places others mentioned, xanthan gum and lecithin are available from places that carry Bob's Red Mill products, or you can order it from them - www.bobsredmill.com.
I use xanthan gum in gluten-free baking. It acts a little like gluten in GF breads. It's also a good GF thickener. I also add it to yeast breads containing wheat flour because it aids keeping it soft longer than normal, but a little is all you need. About 1% (using baker's percentages) in bread increases springiness, loaf volume, crumb softness, and as already mentioned, aids in drying out as quickly. Xanthan gum may also make the dough more difficult to handle.
I'd suggest lecithin granular over liquid lecithin for baking, just because it's easier to handle. Liquid lecithin is difficult to measure and really sticks to the spoon. If you spill any, it's a lot of work to clean off any surface it's stuck to (use hot water to wash it off). Liquid lecithin also can go "off" easily because there are other oils in it (soy oil). Granular is more shelf-stable because it's been defatted, but I would still keep it in the refrigerator or freezer in an air-tight container, and use it quickly.
I buy Bob's Red Mill Xanthan Gum at Whole Foods for my GF baking as well. I've looked into online sources, but by the time you add shipping it is more expensive. Would love to know of any sources with cheap or no shipping.
It lasts a long time because you only use a tsp or two at a time. I do keep it in the refrigerator.
Thanks, folks for useful info(as usually;-) I bought some spelt flour and found interesting recipe. It calls for lecithin, and some folks also reccomend to add some xanthan gum when dealing with spelt. Plus I am going to bake it in bread machine(the recipe is for bread machine). I also later want to try some recipes Grainlady wrote about, but these do not ask for these ingredients. So we will see how it goes. Thanks a lot again.
