Definitely Leek and Potato
nettle soup, for I have never grown enough produce to make soup.
I usually have Nettle Soup each spring but foraged from the hedgerows. I try to not have that many growing on my plot.
At the moment it's spicy parsnip as well as the aforementioned 'Allotment'. My favourite 'non-allotment' depends on what's to hand and the time of the year...
