Dosing can with a straw. Straw sealing a bit pure, with fingers upper end and you've got a drop.
I've done me a droplet on a piece of baguette. While it burns really strong and I have a precaution equal a cup of cream and a cup of yogurt held up - but there were no tears :)
I had sharper Chilli in the garden. But perhaps it is only the dose - the extract I was really extreme caution in the dosage - in the garden Chilli it was possibly the amount by then was a subjectively higher sharpness. In any case, the sauce has steam.
And I have another use for it.
We have voles / water voles in the garden - I can not get the critters away.
I have instilled the extract to small flow-squares and placed these squares in the Wühlmausgänge.
After dusk there were already busy driving. I think that it could work.
I'm still a bit on the approach - but I think you can spit the critters in the soup :)
