My mom and grandma make the best fluffy pancakes hands down! Living in Canada, I haven't been able to replicate it as their recipe calls for use of kefir, a type of fermented milk product (they do sell it in stores here; although close, it's not quite the same in my opinion).
Finally, about 6 months ago I came across this recipe that yields awesome fluffy pancakes that everyone in my family can't get enough of! Try it, and I'm sure it will become your new Sunday favourite.
