We’ve blogged on this subject before — every banana us North Americans eat is genetically the same, since they’re produced from existing bananas. That’s just the least expensive way to do it — the seeds themselves are tiny and next to impossible to do anything with.
You may not know that your grandparents ate a different variety of banana, and your grandkids may eat a yet different variety.
If you have an ethnic produce store or a particularly great produce store nearby, there are other varieties of bananas to try. Even regular grocery stores often now have the very pleasant little red ones. Give them a try!
