About tomato paste measurements
Concentrated tomato paste is thick enough to hold a spoon, with a reference density near 0.95 g/ml — one tablespoon is about 14 g. Tube pastes are often more concentrated than canned, and pressing the paste firmly into a spoon, since it traps air pockets easily, is the only way to measure it repeatably.
