I got this recipe from my mom, who got it from my brother in-law, who got it from his mom, who got it from a lady in her ward (Bertha Stromberg, who is insistant in getting credit for this recipe). It just goes to show that it is definitely a recipe worth passing along!
Here is the original recipe: http://chrisyscookin.blogspot.com/2009/07/lemon-ice-cream.html
(Chris is the queen of delicious desserts. You may want to check out her cooking blog :)
When I make it this is what I do:
3 cups whole milk
1 1/2 cups Half and Half
1 1/2 cups sugar
1/2 cup fresh squeezed lemon juice (3 or 4 lemons depending on size)
and if I have it, a few drops of lemon extract. But it works fine without it.
Combine all ingredients and freeze in an ice cream freezer.
