Harissa powder to paste How much harissa powder would be equivalent to one teaspoonful of harissa paste? 

I have tried to look it up online, but all I can find is "add water and oil to reach the desired result", e.g. here. I don't use the paste very often, so I doubt I will eyeball it right, any quantitative guidance would be much appreciated.
I was just in Morocco and asked some of the owners selling the spice how to do it, the answer I got was:


Add 100 grams of Harissa powder
Add 1/2 cup water
Add 1/2 cup of EVOO


I would add that I have not tested this yet, and 100 grams is a lot to be making at once.
