Mom's Caramel Corn

This is really yummy on popcorn, but I like it even better when made with butter flavored oven-baked Puffed Corn. There are no husks or kernels to worry about and it's the perfect crunch. Either way, this stuff is delicious and always a hit. 

1 c. white corn syrup
2 c. packed brown sugar
½ c. margarine or butter
1 can (14 oz.) sweetened condensed milk
3 gallons popped corn or 1 ½ -2 bags of puffed corn (preferred)
        Combine corn syrup, brown sugar and margarine or butter in a heavy sauce pan and cook to 238°. Remove from heat and add sweetened condensed milk. Blend well, but do not cook. Pour over popped corn and blend well. Form into balls, if desired, or just eat. Yummy!
