To me at least, peaches and nectarines are mostly interchangeable flavor-wise? Nectarines just are firmer and denser, they have a snappy bite instead of a soft one.
nectarines and peaches are actually the same fruit. nectarines are what you get when that branch of the tree develops a mutation that makes the fruit's skin not fuzzy, however. when that happens, they graft that offshoot onto its own/another tree so it's easier to harvest separately.
I 100% do. not particularly a fan of the organic velvet, sad to say, but the fruit beneath is delectable. so nectarines are just like- you took a fruit I already like but had a "meh" trait, and fixed that one trait?? gimme.
Or in the case of pomegranate, juice mixed with cherry juice.
