Another big favourite of ours is this receipe and I just finished making 4 batches for a kids talent show this weekend. It is killing my kids that they can't have any.
Here is the receipe:
1 cup of un cooked popcorn
2 cups brown sugar
1/2 cup corn syrup (light or golden it doesn't matter)
1tsp baking soda
pop all the popcorn and separate the kernals from the popped corn. In a heavy sauce pan melt all together the butter, brown sugar and the corn syrup. After it is melted bring to a boil and boil untouched for 5 min. Remove from heat and add the baking soda... mix a little till it becomes frothy. Poor over the popcorn, you will need to turn it a few times to get it all mixed in. Then pour on to 2 cookie sheets (I like to line mine with parchment paper so I don't have messy pans after) Bake at 195 degrees for 1hr. Place on wax paper to cool.
