Proctor-Silex ice cream freezers
P/S had some really good ones back in the 60s and 70s. Well built and used wooden barrels (works better). Those Rival machines really suck. They're noisy and they either get "stuck" or the gear breaks, thus ruining it all.
Nothing like the old ice and rock salt machines. Nothing really "automatic" about them, they just quit turning when the ice cream gets thick.
4 qt machine recipe
1/2 gal WHOLE milk
1qt. half & half (prounounced "HOFF n HOFF")
a can or two of evaporated milk
6 eggs
2 cups sugar
Vanilla extract
2qt machine, 1/2 the recipe
Seperate the eggs, add milk, yolks, sugar, cook it until the milk starts to rise, add vanilla, chill, run it in the freezer the next day.
Want egg nog instead? add nutmeg and rum extract (or the real thing) and serve hot. MMMM MMMM...
Of course, use a KitchenAid mixer and try to use vintage appliances or utensils, there's no other way.
