What aubergines to use?
Traditionally, the dish is made using round baby aubergines but if you cant get hold of them (as I sometimes dont), use the thin long Turkish ones and cut them in half. Peel them partially to create zebra stripes.
What meat to use?
Ground lamb meat works best! But you can also use ground beef or a mix of both!
Why assembling last minute?
To ensure the bread stays crispy! Also, because Tahini is a thickening agent and aubergines tend to soak liquids very quickly, its better not to pour yoghurt sauce too early on any of the two components. But you can prepare everything in advance and do the final layering shortly before serving.
