How to please Lord Ganesha?

According to one of the tale, taken from the Purana, narrates that the treasurer of Svarga and god of wealth, Kubera, went one day to Mount Kailash in order to receive the darshan of Shiva. Since he was extremely vain, he invited Shiva to a feast in his fabulous city, Alakapuri, so that he could show off all of his wealth. Shiva smiled and said to him: "I cannot come, but you can invite my son Ganesha. But I warn you that he is a passionate eater. "Unperturbed, Kubera felt confident that he could satisfy even the most insatiable appetite, like that of Ganesha, with his opulence. He took the little son of Shiva with him into his great city. There, he offered him a ceremonial bath and dressed him in opulent clothing. After these initial rites, the great banquet began. While the servants of Kubera were working themselves to the bone in order to bring the portions, the little Ganesha just continued to eat and eat and eat. His appetite did not decrease even after he had devoured the servings which were destined for the other guests. There was not even time to substitute one plate with another because Ganesha had already gobbled everything, and with gestures of impatience, continued waiting for more food. Having devoured everything which had been prepared, Ganesha began eating the decorations. Terrified, Kubera prostrated himself in front of the little Parvati putra and pleaded him to spare him, at least, the rest of the palace. Then Little ganesha said "I am hungry. If you don't give me something else to eat, I will eat you as well!", he said to Kubera. Desperate, Kubera rushed to mount Kailasa to ask Shiva to remedy the situation. The Lord then gave him a handful of roasted rice (Attukulu), saying that a handful of roasted rice would quench Ganesha, if it were offered with humility and love. Ganesha had swallowed up almost the entire city when Kubera finally arrived and humbly gave him the roasted. With that, Ganesha was finally satisfied and calmed.
