Combine the water, ketchup, milk, and eggs in a small mixing bowl and mix them thoroughly.
Once you’ve made the batter mix, then pour it into the takoyaki molds and start cooking them.
After 2 minutes add the mini sausages, cooked rice, salt, and pepper to the batter in the takoyaki pan.
Pour more batter to cover the added ingredients until it reaches the brim of the pan holes and overflows a bit.
Flip the takoyaki once the bottoms have dried until they get that golden-brownish color (this means they are ready to be eaten).
Once cooked, place the takoyaki balls in a clean dry serving plate, pour the takoyaki sauce and then serve.
