I had a Madhur Jaffree book that had a much more complicated kheer recipe. It involved reducing the milk by half... which takes a long time.

The following is from a collection of simpler and similar recipes, and is a lot easier.

Wash and soak rice.
Bring milk(s) to a simmer.
add cardamom
drain and add rice, simmer for 10-15 minuites
add sugar
simmer another 10 or so minutes
add almonds
cool and serve
