Okay - so a little more info on the Daiquiri Ice. We found about 3/4 of a teaspoon seems to be about the right amount of Citric Acid...at least for our tastes.
Tonight we made a double batch. It takes about 5 minutes to follow the recipe and make the liquid. We then placed it in the fridge for about 90 minutes with about 15 minutes of that in the freezer. (We aren't the most patient with our deserts!)
When the liquid is ready - it looks just like this. It looks a little darker yet lightens up when frozen.
Now we cheat and use an automatic ice cream maker. This was a gift from Drew's parents years ago and has been well used in our house. They cost under $40.00 now and are well worth it. We also have an extra freezer bowl for when we are making two different types of ice cream.
