Some different, for me, spices

If you've had any experience with either of these spices I'd sure like your expertise on what to use them for. http://i30.tinypic.com/2s76qvk.jpg

The Karangsari is a frim paste shaped into a block. It contains peanuts, palm sugar, chili, citrus, hysterix leaves, tamarind, garlic and salt says it's an Instant peanut salad dressing. I'm assuming I'll add some hot water to a chunk of it.

The Zatar I've used before I really like it on chicken and seafood. It's a powder containing thyme, sumac, citric acid sesame salt. I haven't been creative with this and can't figure out what to do other than season chicken and seafood.

Yes I know GIMF but you guys are so much better.
