A couple of my positives of baby vs. big (regular) bananas:
- Baby bananas are a nice size, if you're a tad hungry have 1, a bit hungrier, then go for 2; the sizes at the market for the regular variety are often too big.
- Sweetness, less bitter.
- They keep for much, much longer. Regular sized bananas last just a few days after you bring them home. I'd say the babies last twice as long, around a week. I don't understand why, but they do.
My hubby picks them up in Vietnamese town (Argyle). I imagine these bananas are pretty much the same whereever you pick them up, so then it's just a matter of price and covenience. I think I've seen them at Jewel at Ashland/Wellington, but I can't attest to how fresh or good they are. In fact, I think when I saw them at Jewel last, they were looking sad.
