Berry-Root Soup allows you to make Berry Soup from combining any two berries as a shapeless recipe in a Crafting Table or in your inventory.
To preserve the ideals of the developers, it has the nutritional values of Beetroot Soup making it very unprofitable to consume, but it at least is better than having no use for the berries at all in early-game!
Works with both 5.2 and 6.0 as of 1/8/25. Please reach out if you would like me to keep this updated, but there are many better alternatives to this mod as far as actual mod add-ons go.
