I have a Retro Series Popcorn maker, new. Can you tell me the kettle size in OZ, 2,3,4 etc. I have pre-measured packets given to me that are for a 4 oz Kettle. Thanks Dan Martin

Hello Dan, According to the manufacturer specifications, your popcorn popper has a 2 ounce capacity kettle. so you should be able to take those premeasured packets and by using exactly (close enough) half, get the desired results of pop corn out of your popper.

If you also want to use your own popcorn, here's some directions that will let you do that also.

First, turn on the popper and add 1 teaspoon of oil or butter, you can also use Land O' Lakes Margarine as it doesn't burn the popcorn like most butter will do so this is a personal preference (so you can use whatever your preference is but it must be melted). I've not tried it un-melted but I don't think it would work too well.

Then add ¼ cup of unpopped popcorn, brand doesn't matter. Wait and within 5 to 10 minutes it will hve popped.
Hope you find this Very Helpful and best regards!
