Ethanol?

Due to the fact that spices and condiments are routinly used in cooking or to prapare coffee; you could try hot water extraction or Infusion.

Ethanol at differents ratio (70/30; 50/50) is also usualy used

Given that spices mostly contain volatile oils you could use steam extraction with water or extract with n-hexane

You may use steam for essential oil extraction,water or varying concentration of ethanol in water for preparation of extracts
