We never had much joy growing strawberries either. We'd get the odd treat that you'd pick and eat as you passed the plant but never enough for a decent serving.

I find buying supermarket fruit in general is a bit of a lottery. I don't suppose it helps buying on line. The last 2 bags of clementines I ordered from Co-Op were hard, dry and only fit for the bin.

We tend to think of strawberries (in our case with double cream and sometimes sugar) as a special treat but the fruit are often disappointing.

I don't think I've tried strawberries but I've used frozen raspberries and frozen damsons from an online shop for jam making. I thought it a bit pricey but the jam I've made has been good.
