First time I have grown these, on the recommendation of a Daily Telegraph gardening guru who said they were one of the tastiest spuds out. My dinner guests did not agree. Is it the season/ awful weather ???? We usually grow Winston which are wonderful

I must say, B de F is a variety I particularly rate. But I've always let them grow to full maturity, which at this time of the year is a state they cannot have achieved. Yours are particularly early. Too young, maybe, and therefore have not fully developed their flavour. It's a variety that is renowned for having a new potato flavour in a mature spud. But as a new potato, disappointing, clearly.

Who was this "gardening guru" of whom you speak? Do they know the ways of Potato Fu?

I believe feedling the soil helps the flavour too, plenty of compost / manure / seaweed etc and they all taste pretty good !

I agree with Felix. Belle de Fontenay should be left till fully mature - they will not normally make over-large tubers. Then they will have an excellent taste, particularly good as cold or warm potato salad. Though quite a few years since I grew them, I can't remember ever trying them as "new" potatoes. If you can get tubers, BF15 is even more reliable and tasty than its parent.

By the way, how did you cook them, Mary?
