Start by preping your dish,by spreading butter all around it.

In a separate bowl,start adding the yogart,lemon zest of half a lemon, the suger, vanila,pinch salt,the juice of half a lemon,the egg and then gently mix all, until suger dissolves(can use a simple hand whisk).meanwhile start heating the oven

In the oven,check that it is rising and cooking steadily..keep it in until colour changed start being seen..also texture at the middle surface is firming.(it will be done when a skewer or butter knife come out dry/clean once poked in at centre)

Alhamdulillah, the browning at edges,also the surface cracking is some of the good signs it's good to go...take out on a serving platelet cool completely before slicing and serving with custard or plain hot drink of choice.Bismillah and enjoy!

...Top it up on other deserts!!
