How can I keep ice cream frozen for a picnic?

Well, athletics day, not a picnic.





I would rather not use dry ice (if possible) and not have to buy much (we have a semi-refrigerating cooler, if this helps...).How can I keep ice cream frozen for a picnic?

The night before the picnic, take several gallon zip top bags and fill halfway with ice fresh from freezer, enough bags to fill cooler with ice cream in it. Pour a 1/2 cup of table salt in each bag and mix well.


Do not let ice melt.


Put bags in freezer. Turn freezer as cold as it will go.


Put a dry folded towel at bottom of cooler.


Put bags in cooler just before you go.


Put ice cream in cooler so each side of box has a bag between it and cooler wall. Do not add any ice to cooler, idea is to keep everything dry.


Put a dry folded towel on top of everything and close cooler lid.


Duct tape cooler lid shut.


Turn cooler as low as it will go.


Do not untape cooler until just before serving.





Also, if anyone gets hurt, you have a towel to wrap and an ice bag on towel to reduce swelling - do not put ice bag to skin, it will frost bite. Give them some ice cream too, keeps their mind off the hurt.
Also maybe you can buy or borrow from someone those ice packs which are some liquid in a plastic sealed container. Freeze them first and stick them in your cooler with the icecream. Or even freeze empty pop bottles (with water) and pop them in the cooler too. Coolers work best if they are full of stuff.
You will not be able to keep your ice cream frozen enough with anything but dry ice. If you use ice packs or a ';semi-refrigerated cooler'; you will have a milk shake before you get to your picnic.
Just full a small tub with ice and then put the icecream in and then seal the ice until its ready to eat. pretty simple.
