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

Example Input: So im a little scared, I was cooking some italian sausage links on my cast iron skillet. I cooked them 8-10 min a side on medium , then turned to low and cooked 7-8 minutes a side.I checked the temp on the very middle and they all registered about 170 degrees (This was after they had been on low, at the very end)Anyways I ate them, tasted fine etc...But upon eating another one later, I discovered that there was still a pinkish color in the middle. (More towards the edges). It wasn't a lot....but the thing is I know this thermometer is accurate and I always use it.....Plus I cook them like this all the time. So I didn't understand why it was still a little pink on the inside. Just for reference I stuck the thermometer on the inner most part, I made doubly sure. And they were all checked and all were 170-180 after they had been cooking on low (So it was prolly a high temp earlier when they were on medium)Any ideas? Im kinda scared. For reference these were Sweet Italian Sausages (not sure if that would matter)
Example Output: Italian Sausage still a little pink?

Example Input: I've been looking at a number of kim chi recipes and they all call for 'Korean chili powder'. My visit to the local Asian grocer only yielded 'Asian' chili powder and other nondescript chili powders.Is there a particular chili powder that is Korean? Can I simply use cayenne pepper or crushed red pepper flakes?
Example Output: How does Korean chili powder differ from "US" chili powder?

Example Input: Every time I make jam I always manage to set it too hard. Is there any way to recover it once it's done this?
