We would have thought that you, an Australian, would have a better handle on the British and their weights and measures than we Americans. You, at least, know whether it’s hot or cold outside when they tell you the temperature. Alas, we can share recipes, and more or less the same language, but it all comes to naught – in cooking, at least – if we can’t get our measurements right.

A sachet contains 7 grams, or 1/4 ounce, of yeast. We have also seen it expressed as one dessertspoonful, which is a measure we don’t use in the States, but is the equivalent of two teaspoons, or 10 grams. We think 7 grams is the best number.
