Before worrying about blending, return empty soup pan to stove, on high, add 3 cups cold water, and 2 Tbsp cornstarch. Mix well.
Blend the soup base in the high-speed blender until very creamy and smooth. If you have trouble blending, add water, 1/4 cup at a time until it easily blends, but remains thick. This may take a couple of minutes.
Back at the soup pan, the water should have heated to near boiling. Add 3 cups cooked rice and stir to separate.
Add seasoned salt, cayenne, and pepper.
Return soup base from blender to soup pan and stir in.
Add broccoli and lemon juice.
Season as desired.
Serve and enjoy. Store leftovers in a tightly covered container.
