Yeast substitute

[Guest guest]

I just saw that Elana, of the Gluten Free Club, has noted on her blog that a combination of lemon juice and baking soda can be used as a yeast substitute. Use 1/2 lemon juice and half baking soda to make up the total amount of yeast one would normally use, i.e., if 1 TBSP yeast, then 1/2 TBSP each of lemon juice and baking soda. But add it at the last minute before you put whatever-it-is in the oven.I assume that whatever resultant chemical reaction occurs must be similar to that of combining apple cider vinegar and baking soda, which some recipes call for -- which works pretty well in the bread recipe I use most often (though the amount of vinegar called for is miniscule, less than the baking soda).  I'm curious as to whether anybody has tried the lemon juice/baking soda thing,  and in the half-half proportions.n -- Now available.
