Ketchup measured by distance in 30 secondsSourced
US ketchup grading asks how far it flows in half a minute.
A Bostwick consistometer measures the flow of tomato ketchup for US grades. At 20°C, grades A and B require it to travel 3 to 7 centimeters in 30 seconds. The familiar thickness is judged with a ruler and a clock.
Even a condiment has a measured pace.
