For the ingredients:in the pic,later added an extra egg and bit more milk(about 5 tablespoons more)

While the suger was caramelising in medium low heat,prep set up the rice cooker as an oven and steamer for the pudding!you would need a piece of foil to cover the tin inside the steamer,as well as you need the outer lid

After milk is ready and suger is ready.now let milk cool abit and then add whisked egg.then also coat the tin of caramelised suger at sides and at base,making sure it is evenly thined around the tin upto almost the top

Now add the egg and milk mixture into the caramelised tin an set aside..here a collander was used as a sreamer to place in the cooker.(it was one with a circular base enof to fit a small tin, which fitted well inside it. Also it had handle that could fit on top of rice cooker so that it was hels upright and nt go all the way in because some space was neede from the bottom of rice cooker to be able to add water,to reach just at base of the collander.)see pic for more demonstration

Now the steamer and set up oven was in place.add tap water in the rice cooker to reach (about quater way up the base of rice cooker) that shown in pic put the tin with pudding,in the base of the collander,such that it fits well..then put a peace of foil,tucking it in around the tin so that it doesnt lift up.you can use cover that wud fit on top of tin and wont melt etc.make sure the tin is secured and level.also put the..now switch on rice cooker.then let it heat.

The built heat and coverinsgd will help the steam in as much as you cover and lids fit properly then the cooking process will be faster and more efficient...the pudding will be ready in half an hour upto 40 mins...check half way to see if its getting not wobbly and slightly risen above the initial level

Alos you can here the water in the rice cooker bubbling/kind of boiling under neath the tins.be very careful as the steam build up is increasing and this can burn your hand or arms.put your gace away from the steam also all kids away and make sure the rice cooker is high and at a corner not to be reached easilyyou can now take out your cover and tin gently lift foil and be cateful with heat on the metal tins and foil etc.

Then loosen edges of puddin with kinfe then let cool abit before turning upside down on a prepared plate which has flat centre but lifted edges for the sauce not to spill
