Success!! It came out so ono! And it was easy to make too.
I combined 24 ounces (2 cans) of strawberry soda with 12 ounces (1 can) of 7-Up, a can (14 oz) of condensed milk and 1/4 cup of heavy whipping cream. I put everything except the condensed milk in the 'fridge ahead of time so that they would be cold.
I put half of the mixture in the ice cream maker and let it churn. I covered the puka on top with my Marukai flyer 'cause I wanted it to stay as cold as possible.
After about 1/2 hour it was ready. Luckily, Leslie has two freezer buckets so I could do the second batch right after the first.
Whatever we didn't eat right away, I put in a container and threw it in the freezer for later.
I wondered aloud if I should get me an ice cream maker, and Landon said that it would be too dangerous for us. Unfortunately that's only too true.
