MOUSSAKA A dish common to Turkey, Greece and the Balkans, made with slices of aubergine (eggplant) arranged in layers, alternating with minced (ground) mutton or lamb, onions, and sometimes tomatoes, often with the addition of a thick béchamel sauce. In some recipes, courgettes (zucchini), potatoes or spinach are used instead of aubergine. The dish is baked in the oven.
This definition from Larousse Gastronomique pretty much sums up my recipe for moussaka. If I were sensible, I would accept it as gospel and be done with it. It would certainly save me a lot of typing and you a lot of reading. But sensible I am not and having looked further into the history and origins of the dish I feel the need to share.
The definition refers to Turkey and the Balkans, but in fact the description which follows depicts the Greek preparation. According to Wikipedia, Turkish musakka is not layered, “Instead, it is prepared with sautéed aubergines, green peppers, tomatoes, onions, and minced meat” and eaten with cacik and pilaf. The Bulgarian and Macedonian versions are layered like the Greek, but contain pork and beef rather than lamb and potatoes rather than aubergine. Like most of the recipes in the rest of the Balkan states, they are topped with a savoury custard.
