Given the background description of some cooking related query, summarize the question into a title

Example Input: At work, when I'm hungry, I sometimes resort to instant soup (Royco, in case it's relevant). Simple to make: heat water, put package content into cup, pour water into cup, stir.However, I often find that the powdered soup has a bunch of wet powder residue left at the bottom of the cup after drinking. although this residue is full of taste, it means the rest of my soup was actually blander than it should be. I also usually have a small bit of residue on my spoon that I can't seem to fully dissolve into the rest of the soup. The residue on the bottom of the cup usually can be fixed through proper stirring, but the spoon residue is trickier.How can I make the soup powder dissolve more effectively so all of the powder is part of the soup?
Example Output: When turning instant soup into liquid soup, how can I optimise dissolution?

Example Input: After I have made my pizza and put the toppings onto it, I find that I am unable to transfer the pizza on to the pizza stone in the oven.When I try to do it the pizza goes out of shape, gets folded, the toppings get messed up and sometimes it sticks or rips. I have tried putting lots of flour under the pizza before I add the toppings but it didn't really help.I am having to make the pizza on a metal tray and then put the tray onto the stone. Put I think that doing this prevents my pizza base from crisping properly.What am I doing wrong? Is there some technique I should use, or am making the dough to wet, or to thin or something?
Example Output: transfer pizza onto stone without sticking

Example Input: I know it's completely basic, but I've been reading up on alternative ways to make chicken wings (admittedly because I've been trying to find a similar recipe to Korean soy garlic chicken) and I came across this recipe from Momofukufor2.It mentions rendered chicken fat, and I'm not exactly sure what that meant. I'm familiar with twice fried wings, so is this just another way of saying "the oil you cooked the wings the first time around"?
Example Output:
What is "rendered chicken fat"?
