That’s it. Eyeball it. It costs pennies to make.
All the animal products are microscopic amounts in the “beef” and “chicken” bouillon cubes, they ALL contain yeast extract, salt, onion powder as 99% of their composition.
You obviously don’t need any of the animal products but you don’t need any of the preservatives, sugar and corn solids either.
Be free from Big Stock and Big Bouillon who have been lying to you all this time.
MSG is a refined glutamate as found in nooch , onion powder and turmeric are also found in this. It is extremely close in profile. The rest are preservatives and a small amount of fat. You can just use those ingredients I put in the description and replicate all the dominant flavors of this disgusting shit you linked.
