Hi Pharon,
I hope you're talking about the pancakes!
There are different
types, or I guess you could call it recipes,...depends on how you look at it. They're both right!
For example, the differences between sourdough pancakes and buttermilk pancakes are minor ingredients,... but they do use different leavening agents..
Sourdough pancakes (like sourdough bread) use a
starter, which is naturally cultivated yeast mixture (basically, you make a paste from flour and water, let it sit for days, and it collects yeast from the air around it, eventually becoming suitable for raising bread doughs or in this case pancakes).
The buttermilk recipe I posted uses a mixture of baking powder and baking soda to leaven the pancakes.
It's the same as the difference between quick breads (like date-nut or banana bread) which you can bake as soon as you mix the batter, and yeast breads which you must allow to rise a few times to develope flavor and texture.
Jeez, I hope you were asking about this, cause if not, I just bored myself to death typing about leavening!
Hope this helps
