My Dad has a weird allergy to strawberries, he can only eat English ones Can't be Scottish, Welsh or Irish (ie: can't be British, has to be English specifically) or any other country's strawberries. He comes out in a massive rash if he eats non-English ones and we've tried him in blind testing where he didn't know where each strawberry was from and yet the rash only appeared for "foreign" strawberries Must be something special in the English strawberries!
Oh and for the best strawberries, you should grow them yourselves! Likewise for the best raspberries too!
The middle European summer started too late to guarantee a good strawberry summer. All we have here in Germany for example are either weird little ones with no taste or imported ones from Spain with no taste.
I“ve once sold strawberries from a local farm in a little stall on the sidewalk. I was allowed to eat as much as I wanted...BEST. JOB. EVER!
