So today my kids, the kids I babysit and I attempted to make homemade ice cream in coffee cans.
Here's what we used:
1 large coffee can (3# size) with lid
1 small coffee can (1# size) with lid
3 Pints half and half
3 tsp. vanilla
3 Cups sugar
We placed 1.5 pints of half and half in the small coffee can along with 1.5 tsp. vanilla and 1.5 cups sugar. I duct taped the lid on to ensure a good seal and placed the whole thing inside of the large coffee can.
Next, we added ice and salt to the large can and placed the lid on. The kids took turns rolling the large can back and forth on the porch for about 10 minutes.
After 10 minutes, I checked the mixture. I could still see it was very liquid through the lid, so back to rolling it went. Another 10 minutes and it was still very soft- like a milkshake.
The kids were anxious, so I divided the milkshake up and let them taste it. We had prepared a second can of half and half mixture and I had it in the freezer to get a head start while we mixed the first batch, so I figured I'd roll that one around while the kids tried the first attempt.
The kids loved the first batch taste-wise, but they were ready for 'the real thing'. I rolled the second batch back and forth for 25 minutes. I opened the can to find the exact same consistency I had when I started. It was even runnier than the first batch.
My ice cream making ego was deflated.
I stirred it hoping to feel lumps in the bottom or something, but not a one was found. I tasted it and found the reason for failure was that my seal must have leaked and all I tasted was vanilla and salt. YUCK! Sadly, the second batch had to be tossed.
We had a fun time, got to have some milkshake and learned to double the duct tape next time.
Anyone else ever try this method? Do you have any pointers to share?
