I purchased a new gas stove with the 17000BTU front burners. My old gas stove had the regular burners. My old aluminum popcorn popper, circa 1960(?) has always worked well on the old stove. My DH is the official popper and insisted on using the front power burner. The popcorn is coming out tough and some are partially popped. I have told him to use the gentle back burner, but he won't. Is there a scientific way to pop corn? I use white kernels only, like the taste. But want my tender popcorn back. We need an education in how to pop popcorn... Help!
