Omuraisu (rice omelette) is the quintessential ketchup delivery system.
Step 1: Make fried rice to your taste
Step 2: Before removing fried rice from pan, stir in a generous helping of ketchup. Then spoon a heap of the rice onto a plate.
Step 3: Fry a lightly-beaten egg into a thin sheet. Flip the fried egg on top of the rice pile.
Step 4: Squirt more ketchup onto egg.
Step 5: Enjoy ketchupy goodness. A spoon works best, IMHO.
