The chocolate powder I bought to add in milk came in plastic jar. Now accidentally one must have added a wet spoon to take the powder out. Now the fine powder has changed into sticky big stony masses, which are difficult to take out from the small mouth of the plastic jar. A lot of quantity is left and I don't want it to waste. Right now what I do is put a spoon and try to break a big mass into small chunk so that it can come out from the mouth. Or I try to hammer the mass so that powder can be formed, but that is very much time consuming and my hands ache after this.
Any idea/hack for this?
