Jerry, I was in the same boat as you. I always mixed my puree with a bit of water to prevent the spices from burning.
A few months back a switched to a larger pan, which also meant I was able to start using the chef's spoon to cook with. For me, this sorted the tom puree / spice problem, as I was easily able to mash the puree and spices and move around without burning.
So, the net it out, I use the puree as is now, with no added water.
