Thanks for the suggestions. I am not going to be able to get any strawberries worth buying as the so-called farm shops that are not ludicrously out of our way tend to randomly stock up with every fruit and vegetable known to man, so that you'd need to be shopping with Sherlock and Hercule to tell stuff brought in from 20ft away from the Kenyan imports. And it is no use asking the staff, as the 47 teenagers milling about trying to work out how to use the till couldn't tell a Honeoye from a Little Scarlet unless they were shades of nail polish.
The market that I am able to get to, as I have said before, is very nearly worse than useless, and I think rather than buying from a shop with the accompanying throwaway packaging it is probably better all around to find a good manufacturer who buys in more appropriate fruit and processes it more efficiently. And I get an extra stock of jam jars to use for other fruit
I don't think I need to beat myself up too much if I buy stuff that I *could* make as long as the maker is in a position to do it better. WI markets would be a good idea but they are on during the day during the week when I'm at work and a show is another trip in the car . I'll look at the Frank Coopers and the Meridian one and see where the St Dalfour comes from - thanks for the recommendations.
I like your logic, makes perfect sense.
I felt a bit guily about the packaging on the ones I bought from Budgens (they do say "local" though). But the clear plastic punnetts will probably get used as propagators next spring, or I might even grow salad on the windowsill in them over winter, so not destined for landfill just yet.
