and how do u test for fat in them too co u like have to crush them first or just add ethanol or what?

Take two equal pieces of the biscuits in a test tube, and either crush them or break them into smaller pieces. Add ethyl alcohol to the two test tubes along with water. Tube with colour change first or more has more fat content.

Note that the appearance is cloudy and milky so its better if u say that the tube with the more coludy appearance.

hope this helps
