When I cook pilau rice I use CurryHell's recipe, here:
http://www.curry-recipes.co.uk/curry/index.php?topic=6070.0 but I batch cook a large quantity and freeze into takeaway tubs because I find it by far the most time efficient way of doing it. So I thought I'd take a few snaps of today's batch as I cooked it, in case it's of interest...
This isn't really a recipe (hence not posted in the recipe section), more a rough guide and illustration of how I've scaled CH's recipe.
First get that oven on at fan 160 deg C and pop a large (5 litre plus) casserole dish in, with 75ml oil inside it.
Now measure 1 tsp cloves..

1 tsp fennel seed..

1 star anise

1 black cardamon

a few green cardamon...

about three quarters teaspoon white cumin and half teaspoon black cumin

1 teaspoon salt...

some small pieces cassia bark

asian bay leaves torn into pieces

tip these spices into the preheated casserole dish and oil and return to oven for 5 mins..

Meanwhile measure out 6 large mugfulls of basmati rice, about 1250g and get 2 litres of water on the hob to boil

pour rice into the casserole dish to join the oil and spices

pour the 2 litres of boiling water into the dish, mix then return to oven for 15 mins, after which it will emerge looking something like this...

add food colouring of your choice... I used red, pink, yellow, orange, green and fairywing transparent colourings. I might've lied about one of those though...

turn oven off then return dish to oven for a few mins to set the colours. Leave to cool for up to 2 hours then mix through to distribute the coloured grains...

Portion up into takeaway tubs ready for the freezer...

the above quantities (6 mugs rice, 2 litres water, etc) are what I call a batch, and today I cooked two batches to produce the yield shown in that last photo (23 portions). These will freeze to give me a handy supply of rice I can grab from the freezer and microwave for 3 mins to produce perfectly acceptable pilau. One point to note, most people would probably add more salt than me, I prefer less so only use 1tsp for quite a lot of rice.
