I've made a couple of batches of muffins and a pie. These blueberries were grown in Mexico (and certified organic by the USDA). I don't know what variety they are, but the blossom end is not smooth. That's a minor negative, but it is outweighed by the flavor, which is better than the Tifblue and Delight I grow. I have a Premier growing at my mom's, and it has a better flavor than Tifblue and Delight. I would have to compare it side by side with these to know which is better, but I think these might have a stronger blueberry flavor, the standard being the low growing wild ones we found as kids.
Hurrah for blueberries!
