I used veg water for gravy, but now veg are steamed or roast there’s not much value in it. . I do use the water from the steamer, because it’s already boiling, but that’s a fuel saver.
Does any goodness percolate down into the steamer water?
The water from the steamer is worth using, I always add cauliflower/broccoli stalks etc to the water for extra goodness.
I use the old fashioned descaling method and add gravy browning and a little cornflour.
I just looked up the ingredients of gravy granules;
