Someone suggested this recipe to me recently and so I tried it out today. I trusted the reviews and quadrupled the recipe for freezing. I'm glad I did as it's awesome. Perfect with a grilled cheese which I then chopped up into cubes and put into my bowl. Yum. It was awesome by itself too and my OH and GG were also both fans. Make it now!
Personally I kept to the low side of the sugar addition as I'm not really a fan of sweet savoury foods. I ended up adding 3T for the quadrupled recipe (I meant to add 4 but forgot I guess) and imho that was just right.
