Makes 1-1/2 pints

¾ cup sugar

¾ cup water

2 cups evaporated milk

½ teaspoon vanilla

¼ - 3/8 cup lime juice

Boil sugar and water to a thin syrup.  Cool and put into ice-cream can with the milk.  Add vanilla and lime juice.  Freeze with 1-to-8 salt-ice mixture. 

Note: Ice used in the freezing mixture should be finely cracked.  For cracking, a heavy sack and a wooden mallet are very useful.
