Regularly once a year, I extol the virtues of the Walnut. To me they are nature's panacea.
The roads and hedgerows are strewn with crushed or half-hidden Walnuts at this time of year. Some farmers gather them; others can't be bothered (they have Chestnuts to deal with) and they just leave them to all-comers.
I always gather about 15 kilos, this sees me through the year; usually with a few left over (they make very efficient fire-lighters). I try to eat half a dozen every day.
Walnuts also make wonderful oil, and I drink two teaspoons every morning. Whether this will assure me the everlasting youth that I'm promised, I'm not sure; but I'm hoping so.
They can also replace Pine Nuts in home-made Pesto.
Wonderful things Walnuts!
