Note that these are subjective terms (small, medium, large particle sizes). Note when I discuss stirring, I'm using a spoon. In each of the following definitions I am stirring the solutio. If using a frother they dissolve about 2-3 times faster.
Color Definitions (from lightest to darkest): This is hard to do, so if you can think of better descriptions then please advise.
- Bright White: The color of table salt
- Fresh Cream: The color of fresh 100% cream from milk. Also the color of bleached flour.
- Banana Flesh: The color of a freshly peeled banana flesh (standard banana in American grocery store ... sorry, too many to pick from). Also the color of sesame seeds.
- Egg nog: Egg nog color
Particle Size Definitions
- Fine: Powdery ... when a cup of it is dropped from a height of about 1 foot there is a large amount of dust that stays in the air, and even upon close up view it is not obvious that the individual particles are crystals (of course they are crystals ... but they're fine enough that they don't visibly sparkle at all). Fines dissolve almost immediately even with cool water from the faucet.
- Small: Small enough that it's not immediately apparent at a quick 1x glance that they are crystaline in nature (of course they are ... it's vitamin c after all, but if you didn't know what that it was vitamin C it doesn't tend to sparkle enough to make that apparent). On closer inspection (still unaided) they do appear as minuscule crystals, but they are not excessively powdery (no dust), unlike Fine particles. Small particles dissolve after stirring in hot water for just 10 seconds or so, about 20 seconds in cool water.
- Medium: Large enough that at a quick 1x glance it is obviously crystaline, as it sparkles when you adjust your viewing angle with a bright point light source. Roughly the size of table salt crystals. Takes up to 30 seconds to dissolve in hot water, and a minute or more to dissolve in cold water.
- Large: About 2x the size of medium (2x the crystal size of table salt).
