:A hydrometer will allow testing of the liquid component, but presumably you're interested in the whole dish.

Hypatia is given credit for inventing the hydrometer ( or hydroscope ) sometime in the late 4th century or early 5th century.
43.
An optional hydrometer window is visible by the single jumper clamp . ( The black negative jumper clamp is not shown .)
44.
He studied new hydrometers ( to measure the level of a river ), rain gauges, and hydraulic operations over rivers.
45.
However, the hydrometer also displaces air, and the weight of the liquid and the air are affected equally by elevation.
46.
The alcohol content of the spirit can then be measured using a hydrometer and tables of density of alcohol and water mixtures.
47.
The development of hydrometers and thermometers changed brewing by allowing the brewer more control of the process and greater knowledge of the results.
48.
Since the floating hydrometer is in static equilibrium, the downward gravitational force acting upon it must exactly balance the upward buoyancy force.
49.
As with the hydrometer, it is possible to use these tables to calibrate a refractometer so that it reads directly in �Bx.
50.
This is a paradox if the buoyancy of the hydrometer is said to depend on the weight of the liquid that it displaces.
