Ive started eating some carbs post workout for huugness purposes, so in cases where im just tooo lazy to bake/boil a 4th batch of tubers in 1 week, i bought some jam.
In fact its 'fruit spread', 50% fruit(black raspberry(!) or blueberry) the rest is grape juice a little pectin too. Im hoping for a good % of gluclose in there, and some phytonutrients if they havnt all been boiled out.
Very convenient too.
