A very little butter can go a long way when applied right...
or is it a butter extract (a liquid butter buds type product free of objectionable stuff)?...
JUST LIKE there is FAR LESS sodium in potato chips than in the good old days! Now it's just a very light amount on the OUTSIDE of the chips ONLY and still has impact!
Moreover, I'll wager that a canola, cayenne, & secret spices blend could JAZZ up popcorn to spectacular heights! And be highly acceptable to nutrition-geeks!
