I’ve just read a recipe that referred to a measure “dstsp”, which confused me for a minute. dstsp, aka dsp, stands for dessertspoon.
A teaspoon (tsp) is the size of spoon you use for stirring tea or coffee. A dessertspoon (dsp) is the size of spoon you use to eat cereal or soup, while a tablespoon (tbsp) is the size of spoon you use for serving food. Put another way a level teaspoon contains 5ml, a dessertspoon 10ml and a tablespoon 15ml.
