I never tried the sovex brand, so I don't know how they compare, but yesterday I found a smoked torula yeast called Bakon at my local Walmart. It was in the section with the canned vegetarian meat products. I know that not every Walmart has this section, so I'm not sure how widely available it is. The manufacturers website is www.ohly.com.
I was intrigued by it, but I am not really sure how to use it as far as amounts, applications and when to add it during cooking. I am fairly new to vegetarian cooking. What were your favorite ways to use the smoked yeast? Any tips would be great.
