I have a gas stove so take that into consideration. An electric may take more time to heat.
In your pot dump:
1/4 cup oil
1/4 cup sugar
1/2 cup kernels
Mix up with long wood (not metal or plastic) spoon.
Lift and shake side to side and up and down.
Put on burner, Count to 5.
one one thousand, two one thousand...etc.
Lift and shake....blah, blah, blah
Put on burner and count to 5.
Do this over and over till the popping slows and stops for 2 seconds.
NOTE: Be careful of unpopped kernels. They stick to the popped kernels and you don't know it till you bite down. I will not be held responsible for broken teeth! Let your kettle corn cool down and then break it apart gently. This should help dislodge those unpopped kernels.
This is my bowl, get your own!
