If you do this event:
Do not steam buns, buy fresh that day. Make sure you have your supplier hold you an order of buns needed. If you buy from Sams and they have those buns I use (Country Hearth) they do not need steam.
Run one pan to hold cooked dogs and one with water boiling alll the time to keep dogs cooked. Better to use pump style mustard and ketchup. If not I would make sure I have plenty of squirt bottles full and on hand. You DO NOT want to be filling bottles when you are in the middle of a rush. Take more than you think you will need, it is not good to run out of anything.
One person to the left opens buns and puts them on trays, middle person (at the steam table) places dog in bun, person to right puts on mustard and ketchup and hands off the dog to customer. Three people works best for this but two could do it with a little extra work…..
