Blueberry crisp dirty soda

Toast a couple tablespoons of rolled oats over medium heat a couple of minutes, flipping them in the pan, until golden but not too dark.

Add chopped walnuts and toast about 30 seconds more.

Pour in blueberry juice and white sugar, add a couple cups of fresh blueberries and about a third of a cinnamon stick.

Bring to a simmer, adjust the heat and simmer about 20 minutes.

Cool and strain; this syrup is the thickest and thickens more in the fridge, so stir before use or thin with a little blueberry juice.

Flavour with butter extract, a pinch of salt and a small squeeze of blue gel food coloring.

Fill a glass with ice and add cream soda, then top with summer berry sparkling water, in a few additions because of the fizz, leaving room for the syrup.

Pour in about three tablespoons of the syrup, taste and add more as wanted, and stir with a bar spoon.

Add a splash of half-and-half, pipe whipped cream over the top, garnish, and add a straw.
