(Antonia)available by the sachet

Yes, so you can buy sachets of that stuff!

I suppose"sachet" in this context just means "packet" -- maybe that's the British usage. In the U.S., the only use I'm familiar with for "sachet" is a little packet of dried flowers that you put in a drawer to impart a pleasant scent. I'm glad to know that I could have miso-scented underwear anytime I want!

Yes, Khoff, sachets are small packets, but not just for dried flowers that you referred to. I don't know if it is limited to BrE, but I've seen the word used very often in cooking and medicine. For example, you can buy sachets of soup powder that you can mix or water to have a quick to make soup. Or when you buy an easy to make Tiramisu, you'll find a sachet of ready-made caramel inside the packa

A quick survey of the items in my kitchen confirms that things here (like powdered soup mix, instant oatmeal, instant hot cocoa mix, etc.) come in packets or envelopes -- not sachets.

That was something new to me! Thanks Khoff.

Thanks to you both, I love this food debates.
