Two loaf pans of water have been in the chest freezer since Tuesday, and Ryan has asked twice now whether they're meatloaf. They're ice. On Sunday we leave for a week in Charleston, about seven and a half to eight hours in the Pilot depending on stops, and those two blocks are the bottom layer of the cooler.
We're staying at a rental with a kitchen, so the cooler has two jobs: feed four people on the road, and carry the first breakfast so nobody has to find a grocery store the night we arrive. The goal is simple. I don't want us eating gas station food twice in one day, and I don't want to pay for it either.
Our main cooler is a 52-quart hard cooler with a drain plug and wheels, bought in 2019 for $48 after the lid hinge on our old one snapped at a church picnic. A small soft-sided cooler, about $18 a few years back, holds drinks and rides on the floor between the kids, so the big one stays shut. A $5 refrigerator thermometer clips inside the big one. That's all of it.
Ice: blocks, not cubes
Here's the why. Ice melts from the outside in, so the more surface touching warm air, the faster it goes. A bag of cubes is a lot of surface. A solid block of the same weight is very little. Blocks last most of a day, and cubes turn into cold soup by lunch. I freeze water in loaf pans for three days, pop the blocks out the night before, and freeze half our water bottles too. They count as ice until they're drinks.
The night before, I pre-chill. A bag of store ice goes into the empty cooler in the garage with the lid shut. It pulls the heat out of the walls, so the real ice doesn't spend its first hour cooling plastic. In the morning that bag moves to the drink cooler.
The order things go in
- Block ice, flat on the bottom, with the frozen water bottles packed around it.
- Things we won't open until tomorrow: a pound of bacon, butter, a dozen eggs from Deb's hens in a hard egg carrier, a quart of pimento cheese and a half gallon of milk.
- A small wire cooling rack, laid across to keep the next layer up and out of any meltwater.
- Lunch: pimento cheese sandwiches in a hard container, boiled eggs, grapes and carrot sticks.
- Breakfast on top: sausage biscuits I bake Saturday night and wrap in foil, because we eat those in the first hour.
Snacks ride in a canvas bag up front: cheese crackers, a bag of trail mix and a loaf of Nora's banana bread, sliced. Nothing in that bag needs to be cold.
The drain plan
Everything that could get soggy goes in a hard container or a doubled zip-top bag. Meltwater soaks through anything that isn't sealed, and it picks up whatever was on the outside of every package in there. At every gas stop, roughly every two and a half hours, I open the drain plug over the grass at the edge of the lot and let the water out. Then I check the thermometer. It needs to read 40°F or below.
That number is the food safety part, and I don't bend on it. If the cooler reads above 40 for more than two hours, or for an hour on a day in the 90s, the perishables go in the trash, no arguments. The cooler rides in the cabin behind the driver's seat, out of the sun and never in the cargo area under the back glass.
The travel day's food for four, breakfast, lunch and snacks, comes to about $30 out of our own kitchen. Two road stops for four people usually run us more than $60, and we arrive feeling it. The rest of the cooler is groceries for the rental that we'd be buying in Charleston anyway, just from our own fridge instead of a store we don't know at 6 p.m.
What I'd do differently comes from the first long drive I ever packed a cooler for. I used bagged cubes, put the sandwiches on the bottom and let the kids open the lid every forty minutes for a juice box. By lunch the sandwiches were floating. Blocks on the bottom, drinks in their own cooler and lunch up high fixed all three problems.
The loaf pans come out of the freezer Saturday night. The biscuits go in the oven right after. I'll report back from James Island on how the ice held up.
