Blackberries were on sale for 89 cents/pkg. I almost made a cobbler, but it was pretty hot here when I made this, so frozen yogurt sounded more refreshing.
I sort of experimented with the recipe, and it turned out well. It was also really easy.
Blackberry Frozen Yogurt
(makes 1-1.5 qt)
about 1 cup blackberry puree (doesn't have to be exact)
1 32-oz. container of plain yogurt
1/2 to 1 cup sugar (to your taste)
1) Make blackberry puree: Puree washed berries (2 containers' worth) in food processor or blender. Strain seeds out with mesh strainer.
2) In medium bowl, stir yogurt and sugar together well.
3) Add blackberry puree to yogurt/sugar mixture. Stir until combined.
4) Freeze in an ice cream maker according to manufacturer's instructions.
