Drinking one restores 6 hunger and 1.2 hunger saturation and returns a glass bottle. Can be drunk even with a full hunger bar. Drinking a berry syrup bottle takes 25% longer than eating other food - 2 seconds - and has a honey bottle sound. Stackable up to 16.

Now you can make biscuits from berries!

You can see berries on the cake, so why aren't they in the recipe? And the recipe is rebalanced.
