CD, I haven't yet been to my local French deli, but tbh my hopes aren't high. It's a refridgerated thing, I'd expect, and they don't stock much of that.
But I have looked in Moro (the cookbook), and there are a few decent options in there. La Belle Boucherie, 3-5 Bell Street, 020 7 258 0230, Damas Gate, 81-85 Uxbridge Road, 020 8743 5116, le Maroc, 94 Golborne Road, 020 8968 9783, le Marrakech, 64 Golborne Road, 020 8964 8307.
Some of the others look possible, but I bet you'd find it at one of those.
