the recipe is from gourmet magazine. i would purchase this magazine for that recipe alone, but in fact it has so many that look good. here is the recipe:
sour cream ice cream
from gourmet magazine (july 2009)
1 tub chilled sour cream
1 Cup Chilled Half & Half Cream (I used Light Cream and it was fine)
3/4 Cup Sugar
1/2 Cup Chilled Heavy Cream
2 tsp Fresh Lemon Juice
1/2 tsp Pure Vanilla Extract
Puree all ingredients with 1/8 tsp of salt in a blender until smooth. Put in your ice cream maker and follow manufacturer's instructions.
This is the perfect summer dessert. With pie would be even better, but alone is perfectly alright too.
