When I was very small there were two special treats that were mostly kept for our parents; in our house anyway.
Our own home-grown Asparagus was almost exclusively for my father; the garden produced very few spears, and he was reluctant to share it with his children (I do now understand this attitude). The other rarity was Scallops; they were expensive, and as children we were probably not considered to be 'gourmets', and as such they would be wasted on us (I now understand this too). At the time it all seemed very unfair.
Over the years I've developed a real craving for Scallops, I consider them to be at the pinnacle of gourmet dining. I would rather eat Scallops than almost anything else.
These days I tend to buy them frozen. They are still expensive so hardly an everyday treat, but are on hand whenever one has the desire. Fried in butter for a couple of minutes on either side, they are wonderful.
I should add that I'd already eaten half my lunch when I took the above photo, which is why my plate looks a bit frugal. The Oooohs and Aaaahs could be heard in Toulouse.
