FWIW, I understand freeze-drying. My question is more about how instant coffee is prepared versus brewing. When you brew coffee, you run the water through the grounds while filtering them out. When you make instant coffee, the grounds just dissolve into it?
What am I missing here?
Ah, that makes sense. Thanks. I guess I’ve just always thought it was the grounds that were freeze-dried and somehow that made them dissolve-able.
