Mushrooms and fruits can be compounded to make juices. Put the fruits first and mushrooms second. This can be a more effective way of making fruit juices because it doesn't take 1 minute for each juice and can effectively use 1/3 to 1/6th the actual fruits needed to make the juices in the blender.
^ Like the above you can also do this for seeds. Fruit first, seeds second. Fruit juices can be sold steadily between 15-35 gold on Aries.
