I am allergic to blackberries pies. That’s pies, not pie.
I can eat blackberries just fine. Blackberry jams, cobblers, and pieces of pie, blackberry or otherwise leave me feeling fine.
As far as I can tell, It’s only when I eat the entire blackberry pie (and I’ve only made that mistake once) that I stop breathing and have to be hospitalized.
