Cracked Mexican/Spanish style rice
You have to use the right type of rice - Spanish Rice, (such as Arborio Rice or Valencia Rice). This SA post may be helpful to you. You can buy Spanish Rice on amazon. 

Don't use rice cooker or pressure cooker. You suppose to toast the rice in oil and fry it with ingredient. See this post for more information.

If you want to increase further the "crack-ness" of the rice, I suggest to soak it in water for few hours before rinsing it. Every time I left the rice forgotten in water they end up breaking apart after cook.
