I think the next big innovation for Soylent would be a savory/umami option.
The regular Soylent options are both perfectly edible food, but the cravings I get are always for something not so sweet. I’ve tried to make Soylent more savory with spices, but it came out kind of unpleasant because how the sweetness of Soylent.
I’m fine with something sweet for breakfast and “dessert” but I’d really like something more “hearty” for lunch and dinner.
Maybe it’s because Soylent lacks that “cooked” element that brings out the flavors of spices and herbs.
