Wild blueberries generally have a more intense, more fragrant flavor, with a tangy note and sometimes a slightly astringent or bitter aftertaste, whereas cultivated blueberries are often sweeter, larger, and slightly less aromatic. But of course, if you’ve picked the blueberries yourself, the tart will be much better!
In a classic blueberry tart, the challenge is preventing the fruit from making the crust soggy—but here, that’s not an issue, since the thin layer of almond cream protects the crust.
