I’m an Aussie gal and a scientist so I prefer to use metric measurements. Last Christmas my daughter bought me Michael Ruhlman’s book “Ratio: The Simple Codes Behind the Craft of Everyday Cooking.” After reading this I understood how important it is to have a good set of scales in the kitchen. A metric cup is not the same as an imperial cup but, if a recipe gives a weight, I can work out what to use. My set of digital kitchen scales coverts from grams to ounces and makes this really easy. In all of my recipes I will endeavour to give weights in both grams and ounces.
These may be useful:
1 metric cup = 250 ml
1 tablespoon = 20 ml
1 teaspoon = 5 ml
