Highlighting carlcook’s advice:
dissolve in cold water, ONLY THEN add hot water. The rationale behind it is that aromatics evaporate too quickly when the instant powder is infused with too/boiling hot water.
I used to because I am single and it didn’t seem economical to brew a pot for one cup. Then I found out about the “4 cup” machines like the ones they put in hotel rooms.

I grind enough for a big cup, pour water in it, and decant it to another cup using a fork as a filter. Seems to work fine.
