When selecting items, slide the mouse wheel upward, and you can choose to pile up ingredients, and left click to take them all away.

Click on the side of steam business, and we can see three purchase options. The first item is the game ontology, and friends who want to try can buy this.

The second item is the game itself plus the dlc of the Beijing Cooking Competition. You can watch the video of the game trial and then consider whether to buy it.
