Sambals...what to do with them?
You normally put the paste to the side of the plate and put some on your spoon with every bite you eat, so you can make it as hot as you wnat. You don't mix it through all your food in one go.
In most SE Asian food you put the rice at the center of the plate and bits of the different dishes (and condiments) around it. You then put whatever combination on your spoon and eat it. Don't mix up all the dishes!
Sambal oelek (or ulek) can be used for cooking as well. Just fry it like you would do fresh chili's, with onions and garlic and turn into nasi goreng or so. It might make you cough and sneeze though!
