Strawberries are available year round - we get them from Morocco and Spain outside the summer. They do taste differently and during the off season are less reliably red all over.
Thus I will buy them only in the Summer.
Prices also change over the year.
They're so large, watery, and tasteless, that I grow them myself or go without.
A lot of foods are no longer seasonal, as noted above, but I can't say I can taste the difference. Except for tomatoes and strawberries where I think I can - who knows, maybe I'm imagining it?
Strawberries again I never partically liked even home grown ones. Som modern ones are tasteless especially those available out of season.
