Our grandma was born in Oregon, the third highest cultivator of blueberries in the US, behind Michigan and Georgia. But that is not the only reason this recipe reminds us of our grandma.

Grandma Inspired Blueberry Crumble

The second reason was her dentures. She had “soft teeth” from an early age and consequently, she was sporting dentures before her twentieth birthday. She wasn’t bashful about it either. She considered it a talking point and even a point of pride, for no one else she knew had been wearing dentures for so long.

Anyway, whenever we would go grocery shopping with her, we would pass the blueberries. Then we would joke and ask her if she wanted some, and she would exclaim, “NOOOO, they turn my teeth BLUUUUE!” and then she would laugh, which in turn made us laugh.

We actually have a love-hate relationship with blueberries ourselves. Like Forrest Gump said, “You never know what you’re going to get,” and that is a disconcerting fact about these little indigo orbs. Sometimes they can be so squishy. That being said, blueberries have been proven to have several health benefits, including being high in antioxidants and a low Glycemic Index.

This Grandma-Inspired Fantastic Treat is a deliciously sweet blueberry crumble. It manages to make blueberries delicious and brings a smile to our faces with memories of our grandma.

For the Crust and Crumble

Combine sugar, flour, baking powder, diced butter, egg, and salt in a food processor. Mix until roughly the size of peas.

For the Filling

Whisk together lemon juice, granulated sugar, vanilla and cornstarch. Then pour over the blueberries, giving them a gentle stir to coat. The cornstarch will help keep the filling together.

The blueberries are ready for action. Pour them over the bottom layer of crumble and tilt the pan around for even liquid distribution.
