Fork pressure test:
- Use the side of the fork to cut or cut food into smaller pieces
- Use your thumb to press the food with the bottom of the fork (the food sample is about the size of a fingernail, i.e. 1.5 x 1.5 cm) until the thumbnail turns white and the food will be flattened/cut/changed in shape. Food does not return to its original shape after the fork is removed
