Prepare your graham cracker crust and press it into a round baking dish. Place in the freezer to set.
For the balsamic blueberry layer:
Add the blueberries, vinegar, maple syrup, and salt to a small saucepan. Bring to a gentle boil and reduce to a simmer. Cook for about 5 minutes, until the blueberries have released their liquid and the mixture is reduced down slightly.
Taste for sweetness and adjust as needed. Stir in the vanilla extract and coconut oil. Use an immersion blender, or transfer to a blender or food processor, and combine until smooth.
Let cool for 20-30 minutes before spreading on top of the graham cracker crust; return the dish to the freezer to set.
For the yogurt layer:
Combine all ingredients in a blender or food processor. Adjust sweetness as needed. Once the blueberry layer is set, spread the yogurt layer on top. Return the dish to the freezer to set.
For the pinot noir strawberry layer:
Add all ingredients except for the coconut oil to a small saucepan. Bring to a gentle boil and then reduce to a simmer. Cook until the strawberries have softened and released their juices, the alcohol taste has diminished, and the mixture is somewhat reduced, about 7 to 10 minutes. Stir in the coconut oil.
Taste for sweetness and adjust as needed. Use an immersion blender, blender or food processor to combine until smooth.
Let cool for 20-30 minutes, then spread on top of the yogurt layer.
The tart will be ready to go after the strawberry layer sets for about an hour. Store leftovers tightly covered in the freezer.
Notes
ALCOHOL-FREE: To make without alcohol, use a fruit juice of choice in place of the wine in the strawberry layer. Double the amount of vanilla extract and almond extract, and stir them in after cooking instead of cooking them in with the mixture. (The small amount of alcohol content in the extracts will help the texture of the frozen dessert).OIL-FREE: I originally made this recipe oil-free, so I know it will work if you just omit the oil. But the texture will be a little icy, especially in the berry layers. If you're comfortable cooking with oil, I recommend using it.NUTRITION: Nutrition facts exclude the graham cracker crust.
