Thank you so much for the first review! It really made my day. :)
I think I might need to make the tutorial clearer, but here’s the trick: Press [E] to open your bag and cooking menu. Just click 3 ingredients to craft a dessert.
After closing the menu, you can scroll your mouse wheel to navigate the hotbar, then click the dessert to select it and place it on the floating plate. A seal should pop up then. There are 4 desserts in total right now (3 of them attract animals). Hope this helps!
