Measuring Chicken Boullion?

Usually the measurements on the container will state how much of each to make one cup of broth. i checked some sites and it seems that most of the companies state the same measurements:

Normal size cube: 1 cube + water = 1 cup broth
Powder: 1 tsp powder + water = 1 cup broth
Granules: 1 tsp + water = 1 cup broth
Take this with the measurement that 1 Tbsp = 3 tsp and multiply 2 Tbsp x 3 tsp - 6 of any one (cube, powder, granules).
Although the answer would be 6 of any one (cube, powder, gradual) to equal 2 Tbsp, I would suggest you start with less and add more if needed. I believe when using powder form the "taste" will get stronger after it has set for a while so do not add more than called for.
