If there's a grocery shop owned by people of North-African origin in the neighbourhood, then you'll surely find it there. Or at the market (very likely in Gent (I always thought you live in the vicinity, but in case you live in West-Flanders, I bought it once at the market in Bruges; you'll definitely find it in Antwerp or Brussels)).
I use recipes too, but always try a variation which comes down to adding more spices. When I first started cooking, I was afraid to add too much spices, but now I usually use a lot of different spices (both fresh and dried) when I cook; plenty of them too. It raises your dish to an higher level. But you have to accept that sometimes, the experiment will fail.
