@LeafStar - Every week there is a new Profession-related event. This week it's Cooking! You have to complete your cooking activities (located up at the top next to your regular endless daily activities) before the week is over to earn as many event tickets as possible. The tickets are then used to buy things in the weekly event shop. The shop changes every week to correspond to the current event.
Your tickets are saved if you don't have enough to buy anything, so don't worry about missing out on buying things or not having enough early on. The event will come back in several weeks so you can earn more and get the shop goodies. Just keep completing activities to keep earning tickets!
For the cooking event specifically, you just have to make a bunch of food and then click on the completed activity buttons at the top of your page to claim your rewards. (They'll turn green and will become clickable when you finish the task). We currently have a monthly seasonal event going on at the same time, so to switch between the Icerun Seasonal activities and your Cooking Camp activities, click the little green swap arrow button with the event countdown timer. Try to stick to simple recipes like cooking fish, meat, and eggs, or anything with a gray icon. The green and blue foods may burn if you're too low of a level, and the food will be lost. The higher your level, the less your food will burn, so don't worry! It's just a part of getting started.
Anyways, you can check out a list of recipes
here, and some edited recipes
here. You earn food from different areas on the site, so just explore and play and see what you find! I also have a cooking guide
here, but it's more for earning experience points and money rather than getting started.
