caulking around sink
The caulking around my sink is brown and very sticky. I want to replace it. What type of caulk do I need?

If you want to do a very good job and ensure no water gets to the formica (I'm guessing that's what you have) and swells it, then pull the sink , clean the area, and lay down some Butyl tape. Remount the sink and remove the excess Butyl as it squeezes out.
Butyl is not a good choice for this application, especially in the kitchen. If you look up installation instructions for quality top mounted sinks silicone is the product of choice.
And explain to me why that is?
Maybe it's because anybody can get silicone at Walmart, while Butyl tape requires a little more effort to find and most people have never heard of it even. As far as "quality top mounted sinks" show me a link for the cheap ones that say to use Butyl instead of silicone. :S
I've never seen butyl tape recommended for any sink installation.
As for the tape itself go ahead and use it, but before doing so I recommend you read the material safety data sheet (MSDS) on butyl tape including one of its ingredients called carbon black.
