One of the first quests that you will encounter in Runescape after you finish Tutorial Island is the Cook’s Assistant. The quest starts in Lumbridge Castle’s kitchen. This is on the first floor of the castle in the southwest corner before the stairs. The Cook can easily be identified by his big white baker’s hat. Strike up a conversation with him, and you will discover that he has been charged with baking Duke Horacio’s birthday cake. He has forgotten to purchase some ingredients, and he wishes for you to obtain them for him. He would like some milk, an egg, and some flour.
You will need the following items to successfully complete the quest:
- 1 bucket
- 1 pot
- Milk
- Egg
- Flour

You can easily get a pot, a bowl, and a jug from the kitchen in Lumbridge castle.
For this quest, you only need the clay pot, so grab that as you head out to finish the rest of the quest.
You can easily buy the bucket for 2 gold and the pot for 1 gold at the general store if you do not manage to pick up the free items.
You can get the bucket on your way to the cows.
