This recipe can be doubled, tripled, etc depending on how many you are serving.
My mother made this yummy grain side dish for our family frequently. We loved it! Still do!
A friend of mine decided to use french onion soup mix made with half the usual water instead of the double strength bouillon, and said it turned out great! I would imagine any dry soup mix made with half the water could be used successfully.
*If you can't babysit the barley for 3 hours, you can just put barley and part of the bouillon in your covered crockpot on high for an hour, then on the lowest setting for 6-8 hours. If using the crockpot method, you will have to check once or twice to make sure there is enough bouillon to keep the barley moist.*
Either way, once most of the moisture is absorbed and barley is cooked, remove from heat source for 30-45 minutes to allow the remainder of bouillon to absorb.
