Make my coffee stronger without equipment I just had an espresso at a café, and it really put into perspective how weak my everyday coffee is. All the equipment I own is a blade grinder, and my method is a turkish brew (grind the beans, put them in the cup, pour-over some boiling water, wait for it to sink, done!).

What can I do to get stronger coffee? And more precisely, what will make the most difference?

Note that I am not willing to buy any new equipment or machines; I'm asking about what I can do with what I've got.

Update: tried adding grounds onto boiling water, instead of pouring water over grounds. Here's how it went:

TL;DR: 


   No success, strength did not increase and taste just got worse.


What I did: 
I took my strongest beans, ground them as fine as possible, used two identical cups, divided the grounds into two equal portions (on a separate tray). I put grounds first, boiling water afterwards in the first cup, and did the same thing but backwards on the second one. I did not stir any of the cups after adding all ingredients. After quite some time I tasted both cups, I am now finishing them both up while programming.

Observations:
The grounds on the "water-first" cup took a considerable time to sink into the liquid. Even after the brewing time had passed, much more grounds were floating around there than in the "pour-over" cup. Also, the water-first cup had almost no foam, which the pour-over cup had plenty of.

Results:
The water-first cup was not stronger than the pour-over; if anything it tasted weaker. The taste was quite different too, water-first tasted a bit stale/watery (not much but there was a clear difference). Pour-over had a rounder and more full aroma, liked that one more. And the crema/foam looked a lot better on the pour-over as well.
I see only one possibility to make your turkish brew stronger and that is using more coffee beans per serving. You are using boiling water and long extraction time so almost everything from the coffee gets extracted leaving you this only option to make it stronger.
