An informal unit of volume used in food and drink recipes. Originally the dash was usually a liquid measure, small but indefinite in amount, roughly 1/8 teaspoon or a little less. More recently it has been used as both a liquid and dry measure. Kitchen supply stores in the U.S. and other countries have begun selling sets of "minispoons" in which the dash spoon is designed to hold exactly 1/8 teaspoon, which is roughly 0.02 fluid ounce or 0.6 milliliter
