He said he could make it...

...Raspberry ice cream, that is.

I believed him.

 Without an ice cream maker, and without a recipe, but with a generous portion of enthusiasm and a handful of Raspberries.
I was impressed - it was very tasty!
I asked if I could share his "secret" recipe and he couldn't help his generosity, so here it is:

2 cups Heavy Whipping Cream
1/2 cup Brown Sugar
1/2 teaspoon Vanilla
1/2 cup Raspberries

Stir together in medium mixing bowl,
cover and place in freezer.
Stir every 30 minutes until frozen through.
Eat.
Enjoy!
